Hmm...I watched it ^^
Its not that bad.
But it wasn't that scary.
Spoiler
...but I was a bit disturbed when blondie pulled the vines out of her leg and when that guy had his leg cut off. And the concept of plants mimicking sounds to trick their food is creepy. Personally, I thought they all would have been better of being shot at the begining of the movie.
To everyone that says they heard from friends that it sucked and decide not to watch it and say that they won't because of their friends... thats just sad. You can't critique a movie you know nothing of. Watch or don't. If you don't watch it you have no opinion that matters. Sorry. And I'm glad some are interested.
