There's a good creepy build up with the hot tub scene. Then it just falters off path completely. Doesn't go anywhere.
You can't really tell which character is who because none of them have a personality. So when you're supposed to pick up "the doubles" you really can't because they all look the same anyway.
Then the ending is just a complete let down. The creature sets up all these interesting suicide traps around the house only for the teens to pick themselves off in completely different random way.
Overall, good premise, really piss poor execution. Oh and the monster looks cheap
