If you have seen the original, you kind of know where this is going. And I will continue as if you have seen it. This time around it's a man who has the issue. The viewer might have a different issue though: We go through almost all the same things we did in part 1. Then again, why change a winning formula?

The acting is OK and one can generally say that if you liked the first movie, the same will be true for this one. Predictibility aside, this has its fair share of moments that will freak you out, something the first one was able to do to. There are "contracted" movies that actually have major issues, so I guess we should be thankful for the better ones
