While I like the Transformers movies, I hate it when the humans get more bullshit character development than the robots do. Okay with the first film it made sense, you were introducing it to people who have never watched Transformers, but I think by the second movie they should have got rid of the majority of human characters, and by that I mean everyone but the army.
More things I hate about the Transformers movies would be:
-Optimus saying One shall stand one shall fall, when he's getting his ass kicked.
-Megatron not turning into a gun. HA! No I'm just kidding about that one.
-Really really stupid plots, than again Generation 1 had a bucket of silly stories.
I guess that last complaint is the reason as to why I like all three movies because the movies were stupid and so was G1 and I love G1.
But back to the robots having little character development. I wasn't expecting the movies to be rich in character development like Beast Wars or Animated, but I was expecting that the characters have a sense of purpose about them when they don't.
So at the end of the day, I like the movies, they're stupid, but I like them, but I will always prefer the cartoons, or at least 5 of the Transformer cartoons.
