For alt mode gimmicks, there are 3 fold-down landing gear, each with nicely-rolling wheels that leaves good ground clearance in the front and enough in the rear to not be a belly-dragger. A purple Decepticon symbol on the upper left sets off 2 light & sounds, a fast plane flyby sound with blinking red lights in the cockpit and behind the intakes; and the other is solid lights while it says "no one can defeat Starscream!" I think that line is a mistake on Hasbro's part, the packaging calls out "flyby and air combat sounds" when there's no combat sounds, and that voice line appears in the separate bot mode sound effect trigger.
Alt mode on its own I'd give an 8/10, with points off for the leg kibble and exposed underside elements (it's a stealth plane after all). If this were a voyager-class it'd be a lower score but the size works well in its favor for heft and sculpt, and it's nicely solid, and from a few angles it's spot-on.
Transformation to bot mode is quite a thing to see, lots of flipping elements around and inverting on, no shellmaster nonsense at all. Hasbro's instructions are from bot to alt mode, and some spots they felt necessary to include both text AND photos, which actually helps a little (especially a slightly confusing double-hinge that can be moved in a lot of incorrect ways) - imagine that. Anyway, once you have transformed it to alt mode, getting back to bot mode you'll understand why things are moving and it'll flow more naturally, but there are a few areas that were mistransformed in package so they still won't feel familiar the first time, and it's easy to forget moving some elements since there are so many. Also, the cockpit has to be opened manually to release a panel behind it, this is very important, they sculpted fingernail slots for it, but it's not mentioned anywhere (that panel, btw, can be taken as an airbrake in alt mode should you have the imagination for it, there's even sculpted detail inside). The launcher hand accessory must come off for tf, it might be possible to leave the missiles on but those wings automorph a flip-over so it would require rotation. Oh, and I hope you like the transform-to-bot-mode classic sound, you'll hear it a lot. I think they meant to have the alternate sound for transforming back but goofed here too as it is intended to sound both coming and going.
Transformation is quite good, a lot of stuff moving and coming together in unusual ways. It's like a modern movie voyager mixed with a Masterpiece, and I don't know if that'll appeal to casual fans, but it works for me.
Bot mode is a big boy, a big, wide, tall, heavy robot boy with lots of things going on. Standing with straight legs, Starscream is a head taller than movie 2 leader Optimus and wider too, and I don't mean by kibble! The figure can digitigrade (chicken walk) the legs down by up to an inch and a half if you like that Starscream-gorilla look, I don't so thankfully he stands straight legged quite well. The figure is quite solid, there's some flex but it holds together well, in terms of de-transforming you can move only a small upper wing and fold in the shoulder a little, so it holds up there too. The figure has a lot of sculpted detailing everywhere, almost every spot you look has what appears to be the inner workings of the jet turned into a robot. There's also a few spots of twisted robot internals like other movie 2 figures, each lower leg has a rotating "bone" inside the shin. The figure does suffer a lot of black screws visible in the front, it's not a dealbreaker but enough to be an issue of note. There's a lot of work in getting the overall shape to come together, even fully useless arms and panels that lock together just to get him right. The wings form a backpack that doesn't stick out too badly, but the crotch sticks out the front and stops so early that it highlights the backpackiness of it. The large crotch is the one part I find stands out too much on the figure, it looks like he's got a big frontbutt, and it's just incongruous. The toes spread a little, but are sculpted with stops so they don't splay too far out. Deco removes more of the tattoos while adding more grays and bronzes, but this is a very uncolorful robot, even the purple Decepticon logo on the top of the backpack (it's the transform sound button as well) doesn't add color to the party (nor the tiny green wiring for the light & sound gimmicks that's a bit exposed in the left shoulder). There are 2 spots of red, the pull-open cockpit tab and the robot eyes, more on those in the gimmick section. I find that if I stare at the figure long enough, the chest visually comes apart into its separate elements, but there's enough going on that there's a level behind that.
Despite thin legs and small feet, the figure stands fine, though 1 click out on the ratcheting hips has too much play and it becomes an extremely wide stance. There's strong play in the knees, so you can fuss with that to get good poses, but the hips are already so wide that the slippage on 1 stop out is hard to work with. The legs have the digitigrade articulation we've seen from the movie before, especially on other Starscreams. There's no above-the-knee swivel, but there is a below-the-knee one to make up for fairly locked down feet. The arms are well articulated, rotation above the elbow but not below. The hands have fold-in thumbs on either side of each hand, and are hinged at the wrist and again at the 3 middle finger cluster, though the fingers are so long I wish they had articulated knuckles, they aren't as versatile without. The shoulders are articulated, and connected to outer torso/collar bone sections that fold in, so he can shrug forward quite a bit, enough to just barely touch the opposite shoulder even! The neck can swivel about 45 degrees either direction. Standing up, the figure is so big and heavy it can wobble, but finding solid standing poses is easy, and if you don't bend them in the same direction so the sideways play takes over, the hips can get action poses 1 or even 2 clicks out that look good. The only restriction on motion is a strut that hangs down outside the elbow which runs into 2 small portrusions out the back of the forearms, this is very easy to just move around, and otherwise range is unencumbered.
Gimmicks in bot mode are nice. First off, the launcher hand can be pegged into the back of either hand, it can be left on the hand when flipped up but thankfully it's designed to be pegged into the back of the figure for storage. It looks like the movie version with 3 missiles on either side and 2 pointy prongs in between, plus a larger rotary wrist (non-movable here). It shoots 1 large dark bronze missile, the ones pegged into the back, the range isn't that great mainly due to the weight of the missile, but there's power behind it. Then there's electronic lights and sounds, or "Starscream speaks!" as the box puts it (it feels right to Screamer's ego), when you pull forward the red tab on the cockpit canopy, there is 1 of 2 lines, the "no one defeats Starscream!" with solid red light, and "Decepticons will crush the Au-to-bots" (the spacing on "Autobots" seems a bit weird to me) with another solid light, the voice acting is about 90% close to Chris Latta Starscream. When you pull the tab, it opens and smashes together the cockpit a little, and opens 2 panels above the cockpit with more orange translucent plastic details behind them, and opens Starscream's mouth by moving the upper half of the head. The light shows through the cockpit, the upper chest vent in the middle and side panel interiors, and lights up the eyes a vibrant red, it works quite nicely. The alt mode button is now on the back and works the same as before. The side panels and upper head are spring-loaded so they can be opened by hand, and are quite solid. The packaging claims there's moving gears to be seen in there, but I am pretty sure there's not.
Then there's my favorite gimmicks, which get their own paragraph. A small red tab is on the inside of each forearm, push it back and on the outside of each forearm, a panel springs in half and hinges up a weapon: twin missiles on the left, and a sweet gatling gun on the right. These aren't the biggest gimmicks, but they are fun as all get-out - I love hidden stuff that opens and moves! The extra outer torso articulation really comes alive using these, it makes for a more organic shooting pose.
The bot mode is impressive, it's quite large and solid, not too chunky for this odd movie design, good poseability. I'd give it a 9/10 and again, it gets points that a smaller scale of it might not get away with.
Overall, this is an A- in my book, there are flaws to be found if you look, but the overall balances fun with collectible, it's an exciting Transformer with some creative ideas going on. What works is an achievement, and what doesn't work is generally minor. While not perfect and a few little goofs, there's plenty of big and little stuff to make one easily overlook those. Also, having compared it to the early pic of Masterpiece Movie Starscream, this is the exact same mold, that one just has a different paint job, and while it's nice and classier, that's not worth double this leader-class Starscream figure (although it may have a clean, non-tattooed paint scheme, then you have to decide where your loyalties lie, cash or F-22-accurate paint scheme). Bottom line, leader-class Starscream is a winner.
