It's disappointing so many people were bored by a films attempt to tell a more layered sorry and perhaps that's why the majority of horror these days are terrible. Anyway, from a pair who only made YouTube videos before we have a deeply unsettling film. It is interesting that it is really about the grief of loss and how the power of the hand exploits this in people to gain a footing.

There is indeed a slow build, which is called character development and when it kicks into high gear (you'll know the scene when you get to it) it never lets up.

Please, please ignore the people with no attention span and give this one a solid try.
