I saw it and thought it wasn't as bad as the critics are making it out to be. I've definitely seen worse. My friend won free tickets to an advance screening so we saw it on Monday for free, so I definitely can't complain for that!
I really did think it had an interesting plotline, however, it was a hair too short for all the things they had going on. They could've taken an extra 15 minutes or so to flush out the story just a bit, especially because of the twist they introduce to us about 3/4 of the way in. All that being said though, I think it really was decent. Probably wouldn't have paid to see it normally, but would be worth renting if anyone was so inclined.
I give it a B.
