Shit my pants.

More gory than scary, and what bothers me is that a lot of the gore is unnecessary. Many kills could easily have been avoided by the mad-woman in the movie, and in fact avoiding the kills would've made her job easier. But for the sake of shock-value and disturbing areas to stab people with scissors, they weren't. I don't think this is a very worthwhile film.

Wow is all I can say. Not in a good way though.
I agree with the comment below me, it certainly did have a strong effect on me. And I'm used to horrible films.

The movie itself, I thought, started out as a generic person being chased round their house horror film, I thought the plot was unoriginal and there was no real substance to it. I didn't really, even a bit more than halfway through the film, see where it was gonna go. I was bored to be honest.
Then the final section blew things into the extreme. One of the most disturbing pieces of cinema I've seen personally. The plot twist was unexpected but not exactly original again and like someone below said, there were a few cliches of horror used too. Although disturbing and very disgusting, it still didn't really make it anymore of a better film.

I also thought the dialogue was terribly written too but maybe that was because of the rather bland and dull way the actors who dubbed over the film in English were acting.
