The premise is good. Adds onto The Strangers. But unfortunately that's about as far as this film gets. By no means is it slow, before you know it you're already an hour and 15 minutes in and it's almost over. Problem is you've predicted every move and then BAM! It's over. I wouldn't buy this film. I wouldn't rent this film. But, if you've got 90 minutes and it comes on one of your premium cable channels by all means check it out.
