You know if you go to the IMDB page for the third Transformers movie, you have to expand the Cast and Credits tab and scroll past "Russian Lady, Russian Bouncer, Pimply Corporate Kid, Simmons Tileman, Mailroom Worker, Berated Scientist, Dylan's Assistant & Executive, Engineer's Wife, Nest Guard, SEALx4, DC Mall Reporter, GPS Tracking Coordinator, Bones the Mastiff" and a lot more that I left out just to see the credits for the voices of the Transformers themselves.
Look, I get that you guys wanted humans in a Transformers movie to make it a bit more marketable and friendly to the mass public...but seriously? When you need to scroll past a dog, owned by Michael Bay, in the credits page just to see who voiced the titular characters, something is wrong in your franchise.
Anyway, I can't even remember what happened in the first two and I don't plan on seeing the third one (or at least not paying any money to see it; if it starts playing on TNT or something and there is nothing else playing I'll probably have it on as background noise), which means I doubt I'll have any interest in further Transformers movies unless they take a radically different route to making the movies.
