This was the best scene in either of the movies. I cant completely hate the film because of this scene, the opening, and the end fight with Megs and The Fallen. Anytime Optimus was around it was really really awesome. It's too bad the rest of the movie kind of fell flat.
The the classic lines Prime dropped as he took on 3 Cons was awesome. In the back of my mind I thought I heard Stan Bush! And I kept waiting for Hotrod (or in this case one of the twins) to interfere so Megatron could get his chance to give Prime a fatal blow. "You won't at one!" "I'll take you all on!"
