So I just came back from the first showing at my local theater. I think it's a pretty nice improvement over the last three movies, but if you hated those you probably want to skip this one anyways. The robots get a little more personality and the human interaction isn't mindblowingly awful. Lockdown was a cool villain and
SPOILER: Highlight text to read: surprise surprise, Megatron returns under the alias of Galvatron- how original. Dinobots were cool but didn't get any speaking parts aside for GRRRRAAAAAHHHH and SCREEEEECH. Drift wasn't as stereotypical as I figured (voice and haiku scene aside), Hound was resourceful, Crosshairs was an egoist/pessimist with a punch, and Bumblebee was... Bumblebee. Oh, and as for Prime... suffice to say he was a walking time bomb. It's like he's been holding in all his anger from the previous films, so when he finds out that yet another comrade was lost- he snaps. Hardcore.
SPOILER: Highlight text to read: Seriously. He kills people. Like, humans. He murders them. It was pretty cool.
All in all I think it was $14 well spent.
