I decided to see this one yesterday.
It was disappointing overall and about 50 minutes too long.
The good ?
I really enjoyed and liked the battles and the robots kicking each others ass. Especially the forest battle.
And contrary to many, I had no real problem following the action or see who was the Autobot and who the Decepticon.
I also liked the Autobots working with a military team angle. Soundwave wasn't bad and it was good that Megatron and Starscream got to speak more in this one. And the Megan Fox on the bike scene was nice.
That was about it really as far as the goods in this movie go.
The humor was a failure for the most part, the twins and the mom where useless, stupid, annoying and a complete waste of screen time and especially after they meet the Sector 7 guy the movie really started to drag...
Had they cut the twins, toned down the mom, had less "humor", reduced the length to about 2 hours and done some better editing job this could have actually been fun.
Well, at least we'll always have the robot battles.
