So many things to say but basically if you don't believe in demons you won't be scared. Very long, drawn out and B-O-R-I-N-G!!! A couple of laughs but too much time between the laughs and supposed scary parts.
If you do believe in demons then the subject matter will make you think and you might be a little scared.
Wait for the DVD and watch at home alone on a stormy night if you have nerves of steel and you might have a few hairs stand on end.
