It's this kind of overstatement and willing ignorance of the movie's merits, that I touched on earlier, that cause arguments in these threads. If you didn't enjoy the movie, that's neither here nor there. But, you can't sit there and claim that the 'bots didn't do anything of value in the movie. You just can't. It's blatantly untrue. I, for one, am happy that the Dinobots even showed up in these movies, and that they came out looking and acting as accurately as they did. There was a time, not too long, when that seemed like a complete impossibility. I don't get what's so random and 'out of nowhere' about their appearance either. They were prisoners on Lockdown's ship, Optimus freed them, and they effectively served as the ghost army in Lord of the Rings. Works for me. On top of all that, they're most definitely going to show up in the sequels because... they're giant robot dinosaurs that will easily sell toys. Another thing that bugs me is everyone complaining that "Oh, they don't explain why they have the dinosaur alt-forms", as if a giant robot scorpion and a robot tiger didn't just pop up in the last three movies. It's not like any of the other source material has ever given a thoughtful and not contrived origin for the Dinobots anyway. So, why even bother?
