Most underrated horror film I know of... (I joined IMDb just to say this)

Rating: 10/10 (15 May 2009)

I was so close to not watching this film because of the comments here, but I'm so glad I did, this is the first comment I've made on IMDb, because I had to tell everyone who hasn't seen this film that this is NOTHING like a conventional 5/10 horror film.
I'm a huge cynic with horror films, I hate nearly all post 2000 American ones, but I haven't just sat down and enjoyed one like this since Alfred Hitchcock's psycho (1960). I heartily recommend this film.
To prove you can trust me:
Reasons I think people undeservingly hate it are:
-they are in denial a person would pay to kill a random human being and say this is "unbelievable".
-they think nudity is unnecessary for some reason, (it's not used in anyway to try and expand the target market of the film or any cheap shot like that, they just shows some tits and a bit of sex, which is not a big deal)
-they think the gore was unnecessary because there is not any in the first half (the gore is great and adds to the impact)
-the characters didn't bitch enough (definitely a good thing when I'm watching a horror film)
So please dismiss negative comments about this film. Thank you for your time and brace yourself for a killer film!
