I hadn't seen this movie in years until recently and it retained two things since my last viewing: 1) it's the best Transformers movie that Michael Bay has given us yet and 2) it sucks. A live action Transformers movie should be some of the most fun you could have in a movie theatre, but instead Michael Bay decided to waltz into the project and give us this mess. Who would have believed it, but two crappy sequels later, billions of dollars in Michael Bay's hands and we're getting a fourth film in a couple of days. Typical Hollywood is all I'll say.
The film gives a lazy attempt at cramming in humour, but ends up failing. Transformers is a film that can't even take itself seriously. Action and character drama is what should make a film, not the side humour. In this film they just forget all about that and replace all aspects of drama with mindless, out of place humour that fails to impress. There is actually a scene in this movie where a Transformers urinates on a humour... that's just the tip of iceberg into the world of the endless and embarrassing humour present in the Transformers film.
The cinematography in the action sequences makes it impossible to see anything. The film has two to three action sequences throughout that can give it something to boast, but for the most part the action is useless. The camerawork and editing is so choppy and shaky that we'd feel the same effect if we closed our eyes and just listened. The worst part is that the filmmakers, obviously, haven't heard of a wide shot. The action is never shown in full detail, but instead in a series of fast cutting close ups. The rare times when it slightly zooms out is in those rare moments of enjoyment.
There's little reason to care for the human characters. Shia LeBeouf's character is literally just there so we can follow the story of a human, but his character is just a pain. He's not a bad person, but he's boring to watch on screen. While Megan Fox is, of course, good to watch, her performance is terrible (when is she not though). She's also there to be part of a necessary relationship for Sam, but yet again, it's dull to watch.
To sum up, Transformers could have been something much better than how it turned out. The film replaces a character driven story and plenty of fun action with stupid humour, terrible acting, uninteresting characters and choppy editing.
