Money, violence, sex, computer graphics, scatalogical humor, racism, robots designed to be rednecks but given European accents, and maybe another sequel to the saga... what's not to love? TF m1, Revenge of the Fallen, Dark of the Moon and now Age of Extinction.
Given how contray movie tie-ins are to each other and the movie itself, I am not going to bother taking of too many points. If nothign else, the fact most of those toys are based on AEC molds is a contradiction as well.
