Except that this was foreshadowed as a wrong decision early in the film. However the movie characters don't do anything with it, but as a movie watcher you know it's a big deal. It's frustrating that there is a big clue that doesn't get any exposition (confirmation) until the 'twist' end.
I agree with the general consensus that it starts good, but ultimately fails. As soon as the ghost kids start appearing the film goes downhill. The demon looked very disturbing but was underused.
