I just got back about 2 hours ago from seeing it and I LOVED it. Bumblebee was friggin hilarious with his music near the beginning of the movie where Sam was trying to get with Mikeala (don't really care how to spell it correctly) I was laughing my ASS off.
Megatron, well, what can you say? He was so awesome in the movie, it almost made me cry tears of happiness. I like how they made him a jet now instead of a pistol (seriously, how the hell did a robot his size ever manage to turn into that pistol?)
Optimus looked crazy cool with his new design. Hell, all of them looked really cool.
Megan Fox was useless, as I expected. Sure, she drove the tow truck but what else did she do? Oh yeah, right, walked around half naked and pretended she knew everything about cars. THANKS.
I can't wait for Soundwave to be in the second movie. I love that guy <3
Overall, great movie. I only had one peeve: less humans more Transformers dammit!
