1. Usual stupidity of horror movie characters. What do you do when strange things are going on inside the house? You stay together right? But no, our main characters leave each other all the time whenever something scary happens. An evil spirit is bothering you? Go ask the person you’re with to leave the house then start exploring the place when all the lights suddenly go out. Oh yes, this does seem to be the logic of our main characters.
3. You think the spirit has already left, then surprise! It’s still there.
4. A crawling bad lady spirit. Seriously haven’t we had too much “Sadakos” and “Grudges” already?
