This movie isn't really bad, but there are so many inconsistencies :
I give 3 stars because I don't like nonsensical stories.
- it's easy to guess who the killer is, even if you didn't read the book ;
- people keep doing stupid things ;
- people should stay together, but guess ? They're roaming around all alone ;
- the killer couldn't do everything alone as depicted ;
- there are facts that the killer couldn't know ;
- the characters are way too stereotypical...
