I really enjoyed the first Transformers movie, and the second one was an ok popcorn flick.
I thought "The Twins" was just dumb. Their actions took me out of the movie more than drew me in. Also, there was a ton of sexual innuendo and one f-bomb that just didn't need to be included, IMO.
On the plus side, seeing Megan Fox laying on that motorcycle and all of her slo-mo running was well worth the price of admission.
I saw it once, it was ok. I'll see it again on HBO, but I won't purchase the dvd.
