Transformers 2 is a lot like being stuck in a washing machine on a repeat cycle, along with stones of various sizes, several racists, a few misogynists and a scatalogically obsessed 12-year-old boy.
Renowned auteur Michael Bay focuses primarily on the madonna/whore dichotomy that has so long been a part of western culture. He does this with shots of Megan Fox that would embarrass her gynecologist. He will sometimes cut to her pouting lip, seemingly operated by a length of wire from just off camera. Sometimes something will be blowing up when this happens. Sometimes not. You never know with Bay, and therein lies his genius. I don't know what point he's making, but several of the explosions were very large.
He has space for subtext though - there is a running commentary on the military industrial complex, specifically focusing on how frickin' awesome it is, how great it is to blow stuff up, and how empowering it is to point huge shiny penises that spray bullets wherever you goddamn please. Sometimes representatives of military industrial complexes that are not specifically the US turn up. You'll be able to spot these because they are on fire. Occasionally a robot farts. Sometimes one falls over in a comical manner.
Watching Transformers 2 is a lot like being Alex in A Clockwork Orange, but with Linkin Park instead of Beethoven. Same time 2011?
