Unjustified hate?
Transformers RotF is actually quite entertaining and far better than the first film and think in general very underrated. People complain about the film being too long or just about robots fighting each other with a terrible plot and little storyline, but I don't understand that complaint. This is a transformers film and the main point is to be entertained with as much action and explosions as possible, and for that fact alone it satisfies.
If you want a boring film with proper storyline or bunch of dialogue and no action then watch Woody Allen film.
