Yeah it's called 'The Strangers', and yeah I liked parts of it, i shat at the end though.
Oh yeah the ending..It don't make any fucking sense.
After being stabbed twice in tha stomach and left to die for 2 days, then a fucking boy comes and she's suddenly alive again and screams. I mean comon. Also, start of the movie it says some shit like "Some of the events of this film are still unknown", well if she screams at the end, she must be alive...so I was confused. But I guess I always do this with horror films lol.
