Surprisingly good movie...
… while this particular surprise twist has been done before, I actually found this to be a much better than expected movie. It's no classic, but very well produced and quality acting. Carpenter still has a GREAT knack for jump scares that don't feel cheap and unearned.
People may complain about the very last jump scare … but considering how overly used that whole cliche is, I think he found a good twist on it. Having the scare happen a second earlier than it normally would… worked for me!
If you're on the fence, go ahead and give it a shot...
