although Optimus Prime and Bonecrusher as a very short scene, when you really think about it, it was really the only robot vs robot battle that had a beginning, middle and an end without cutting to other scenes....which also makes it the best Robot on Robot battle in the entire movie. Because in the downtown battle, there was alot of cutting between scenes such as sam running, optimus and megatron, mikaela and bumblebee, devastator and army guys. They cut back and forth alot between those few situations. But for Optimus Prime and Bonecrusher, that was pretty much the best action sequence. It was shown very clearly without the frenetic camera technique and we even saw personality in the characters in such a short time. Such as Bonecrusher being an all-out warrior who lets nothing stand in his way and he hates everything especially Prime that he just jumps into battle regardless of his own safety. And as for Prime, he defends himself strategically using his surrounding as well as other resources available (his sword arm). That fight lasted 40 seconds but we saw it clearly and it told us alot about the characters. We need more scenes like this and longer ones for the next movie. I'm just expressing my appreciation for that scene. It really kicked the excitment level into high gear.
