Exellent movie, very entertaining, cood laughs (some cheap, but who cares) awesome action secuenses and so on... But I think it suffered from the same problem as Spiderman 3, too much crammed into one movie...
and...
Skids and Mudflap were funny imo, but got way too much screentime... and Ironhide and Ratchet barely said a line in the movie, which sucked...Sideswipe was mainly a statist hanging around and Prime was mostly "absent" the whole time, they wacked Barricade in the first 10 minutes and how the hell was Blackout still alive (and to be killed by Prime, I mean didnt he die in the final batle in the first one already??)
Starscream was a slippery weasel like he should, and got his ass kicked by Megatron a couple of times
... Soundwave was pure magic, and so was Ravage, but Jetfire was like Treebeard straight from LOTR, old, in bad shape and kinda senile
... Megan Fox and her new boobs were in the screen constantly (which was nice, but hey this is Transformers) and a whole lot of decepticons were just "hanging" around without a purpose or name just to be cannon fodder in the last battle...
So a good movie absolutely, but too much going on (Fallen, Matrix of leadership, "Super-Prime" the TF "gods" appearing to Sam etc...)
Liked the first one better... but exellent nontheless...
