Boring watch, won't watch again, and can't recommend.
Despite a minor "ghost effect", there's very little that makes this more than a bunch of people going into hysterics and stabbing each other, or refusing to stab each other, or going on about refusing to stab each other before stabbing one another.
I wanted to like this, but there just isn't much to like here. The characters aren't very enjoyable, with a couple exceptions, so I'm happier to see them die than survive.
When it eventually gets to the final survival group, the resolution is like a slap in the face for making it that far in the movie.
