So that happened.
I'm giving this one a quarter star because there was a fairly nice twist and the discovery of the twist was a little bit creepy. Not a lot creepy, but a little bit.
The rest of the star goes to Jennifer Lawrence and her many tight low-cut tank tops.
Otherwise, this movie was utterly predictable, not a bit scary, and full of unlikable characters all around. Plus, there're some "artistic" shots early in the film that are basically just strobe lights amounting to confusing, annoying crap.
Those that like looking at Jennifer Lawrence all sweaty and cleavage-y will be able to endure this film, barely. But if you're not one of us, you should probably just run away screaming now.
