I watched the movie this weekend again (finally got around to downloading an HD copy on Live). I loved the movie from day one, but I just came to a realization of something that had never occured to me before. They never talk in their vehicle modes. The decepticons do, when they are coordinating their attacks, But the Autobots never talk to eachother in car mode. That, not only would have been easy to do, but would have given a bit more "screen time" to the characters we love. Like when Jazz is parked like a horrible friend in front of a legless bumblbee and Sam is pushing him back to give the Bee more room, any line would have worked well, like "Hang in their bumblebee", or when Ironhide is driving towards Devastator, a "I picked a hellova a day to get out of stasis lock". Obviously I'm not a writer, but they could have thrown in some good lines in there. It's what nagged me, that as much as I believed that those vehicles were autobots, them talking would have sold the point even more.
