I'm definitely a movie buff, I can enjoy anything from dramatic artsy films to high-budget action blockbusters. However, I feel this last decade of movies has been mostly junk, and the Transformers series is a perfect example of a movie that is all style and NO substance.
The first Transformers film isn't bad for what it is. The plot, characters, and dialogue are all pretty stock, but it's fun to watch these big robots duke it out and the special effects are more impressive than a lot of recent films. On a scale of 1-10, I'd give it a 6.5 because it's nothing special but it manages to entertain.
Transformers: Revenge Of The Fallen is the 2nd film. I expected it to be about the same as the first, maybe even a little better. On the contrary, it was worse... a LOT worse. The movie basically becomes a comedy full of stupid, immature jokes that only an 8-year-old would laugh at. The plot has way too many holes in it, Megan Fox is nothing more than a stale piece of eye candy, Optimus Prime (the best Transformer) is gone most of the movie, and there's too much shameless advertising of Chevy and Mountain Dew products. The acting is bad and the whole movie is just glamorized crap. I'd give it a 3, only because there was a couple of decent fight scenes.
Transformers: Dark Of The Moon had my expectations in the gutter. It was better than the 2nd movie, but not by a lot. Once again, the film is too long, Sam's character has become less likeable with every film, plenty of brainless over-the-top action, weak acting and dialogue, and Michael Bay's nonstop spinning camera. It wasn't quite as annoying as Revenge Of The Fallen but it was basically the same kind of movie. I'd give it a 4.5
