Good for you. The guy used to make pretty average films but with Transformers he decided to absolutely bat **** insane. Why? No one knows...
I somewhat agree with you. Before Transformers I always saw Bay as an average to slightly above average action film maker whose movies inexplicably make hundreds of millions at the boxoffice.
Bad Boys1: The epitome of a mediocre action film.
The Rock: One of the best action films of the 90s. I think the talented Jerry Bruckheimer had a lot to do with this movie being great.
Armageddon: The film had it's moments but, overall it was a boring, bland, piece of crap.
Pearl Harbor: This was the first war movie I saw in which 70% of the film was unwatchable.
Bad Boys II: I've seen the film in portions. It looks slightly better than the first but, not good enough for me to watch the whole thing.
The Island: The one Bay film I know nothing about.
Transformers: A fun goofy entertaining film. However, the film could have been so much better with a revised script, less pointless human characters, and more transformer dialog.
Transformers 2: The only positive thing I have to say about the film are the special effects and action. Everything else is forgettable.
It's actually kind of weird to see the contrast in styles of plot, pacing, and humor for the Bayformers movies in comparison to Micheal's early work. Micheal did a good job with the humor in The Rock and I thought the majority of the characters were interesting in the film. All of the major and minor characters in that story had a few lines of dialog or scenes that made them look important.
The transformers movies are overflowing with crude jokes/bathroom humor and multiple characters with little to no development. This following video does a pretty good job of describing the thought process Micheal uses to develop the Transformers films.
