Yes, I'll get deep and look ridiculous - I'm not ashamed.

Rating: 7/10 (14 July 2008)

I heard bad reviews and went anyway. My experience is if it draws a violent reaction either way, it's usually worth seeing so that you have an educated opinion.
I am not a huge Shy fan, but I will say that of most of his movies that I've seen (Sixth Sense aside) this is probably the best so far. I'd heard in an interview that he did intend to make a "B" movie and it's obvious - at times bearing the same tone and atmosphere of a Romero zombie flick. It has the same tension and underlying fear, occasionally trumped by some graphic and overt violence. There is over-acting - by talented actors who know the difference, so much so that it is obviously intentional - and the acts of violence are at times amusing because they are either a)completely unrealistic (Lions would not behave that way, I've seen enough Discovery Channel to know it) or b) so shocking so you don't know how else to respond - a reaction I have often when watching particular films.
My husband was adamant about not seeing this movie and, though he remained convinced afterward that it was without a plot and ridiculous, could not say it was the worst movie he'd ever seen (That honor is still held by "Battlefield Earth"). I would say that if you are a 'classic' horror fan, particularly Hitchcock and Tales from the Crypt, can look beyond the message that tree-huggers will glom onto (sorry, lefties, but there was terror of plant life before the environment became a popular topic), possess a bit of a sadistic sense of humor, and can suspend your disbelief for a little while - this movie will, at the very least, entertain you.
