A group of teens barricade themselves inside a house to escape a creep who is a bit of crackpot... It pretty much goes where these types of movie usually go with its usual screaming, darting and escaping. The ending is a bit of a surprise admittedly and it gets extra brownie points for that. But the characters are just... uggh... and also annoying and unlikeable in equal measures. Watchable... to an extend I suppose. Maybe put it on while vacuuming the floor or doing something else
