I saw the movie in IMAX 3D. I loved it. I'm really getting sick of reading reviews, however, that choose to play up the "dur hur its a movie about nothing. Its jus bayformers." shtick. It's stupid and not valid. I mean, if someone doesn't like the movie, great. But the trend has been to just pick on the movie to be part of the 'cool crowd' of cynic critics.
The movie was awesome. I had a lot of feels for Optimus. When he screamed "They slaughtered Ratchet!" ... damn! I felt like the bots got a lot more time to shine this time around; they had fantastic personalities and Optimus got to emote a lot. His character has progressed and there's a solemn aura around him that carries a tragic weight.
Optimus has been through a lot, emotionally as a character and the movies haven't really gotten to show that. But this movie gives us a nice shot.
The Dinobots were just brutal. Loved them.
One drag, though. We never really got to see Drift, Crosshairs, or Hound transform. We saw their vehicle and bot mode but no transformation between the two. That's one of the sellers of the movie for me.
