I think they were a cool concept, but I don't like the way they were done in the movie. 1) I hate the weaponized Nascar modes - they look like piles of scrap metal on wheels to me. I think realistic ones would have been better. Plus, it ruined the whole concept of "robots in disguise." 2) I wanted to see more Autobots that weren't cars. With Ironhide gone, there are way too many car Autobots now. I want some more variety! 3) They were just sort of thrown in half-way through the film, and their introduction was dumb. "Yeah, there are three more Autobots on Earth, but we don't let them off Cape Canaveral because they're arseholes." Yes, that makes perfect sense. They did get some good action scenes, but I still say they could have been done better. What do you guys think?
