The movies actually kinda boring.
I mean it's not that I think the movie is as horrendous as it's made out to be though it isn't a good film either but it gets really boring for the second half of the movie after Optimus dies.
The past two times I've watched this film I've almost fell asleep and that's never happened with anything else. The whole second half of the movie drags so much, the action scenes in particular and they're so repetitive.
It's a good 20 minutes too long.
