For me, watching the movie was like indulging in chicharon while you have high blood pressure; eating cake and drinking softdrinks while you are diabetic; cheating on your wife/husband after just 2 weeks of marriage. It's so wrong on so many levels, but it feels so good you indulge yourself and just forget about it.
The movie has all of it (just too much of it); Megan Fox, military hardware, Megan Fox, explosions, Megan Fox, all-out robot carnage, and Megan Fox.
But it also had robots based on racial stereotypes, a plot confusing as hell, deus ex machina, and just downright unnecessary and flat-out gross scenes (dog humping, the unitard, and a robot humping scene

? I didn't find those scenes funny.). All in all, I left the movie with a headache and all my body parts yearning for a good night's rest (which I didn't get since it was work time after the movie). The movie is I think Michael Bay's ultimate creative orgasm/brain-fart. It had everything in his past movies, multiplied by a factor of 10. People from film schools will look at this film and associate it with words such as 'excess' 'over-indulgence', and 'creative chaos'.
This doesn't mean though that I won't watch it again. After all, what's so bad feels so good, it's so hard to let go.
