It's a bad-in-a-good-way movie. Acting isn't terrible in that its consistent, and who really cares about the characters. You get a bit of backstory with each one - not a lot of detail but just enough - and that is the important bit because with these kind of movies who cares. You know why their lives suck in five minutes or less - why they are willing to go for the random 'you're invited to spend the night in the haunted house for cash' trope thing. There is a decent amount of gore, desperation, a bit of humour, and a decent ending. So grab a couple cans and be entertained for an hour and half.
