I saw the movie Transformers this evening. It has the full entertainment factor: action, special effects, humour, romance . . . In short, I enjoyed it.
There's not a lot of character development though, and I think the only characters I really cared about were the main character, Sam (a teenage boy, who holds the key to preventing the bad 'decepticons' in the form of his grandfather's spectacles), his would-be girlfriend (who has an interesting background and a mechanical bent), and the transformer, Bumblebee, who is Sam's protector in the form of a car.
Nevertheless, it's fun to watch, and the special effects are truly something.
