Horrid flick. The writing was so bad, it would have failed a creative writing class at a community college.
Megan Fox is hot. Period.
The robots are well animated, but they transform so fast that you cannot see what they are actually doing.
Half the time I had no idea which robot was good versus bad.
Popcorn movie, with lots of effects.
NOTHING MORE.
I read a review that summed it up perfectly. It has some NSFW language:
