bad acting!? *spoiler*

i just watched this movie and thought it was fantastic.
i was astonished to read some reviews panning the standard of the acting in the film. I personally thought all three lead characters (especially the girl, the 'worst' actor) did an exceptionally good job. I found them very convincing and actually became emotionally attached to the characters. I actually wanted them to survive, as usually in movies like this i don't really care if there's no character development, however in this i believed there was. I thought the scene where the guy was getting eaten, and the dude and the girl were crying and screaming was brilliant. And when she was talking about nobody being home to feed her dog i actually welled up!
Regardless of what critics are saying about this movie, the damn movie was good and the acting was also *beep* good. what more do they want, just criticising a good movie for no reason.
