Although I give you one reason you might like this or may want to watch it: Gore/effects. But if that is what you are looking for, then do stay away from the German release of this movie. Every "good" part is chopped off (pun intended). But is it enough to see everything being cut, hit or whatever else wicked and sick you can come up with? Tough to say, and only you yourself can answer that question.
Keep in mind though, that you have non-actors in this movie (I really hope they have day jobs and I'm not trying to be mean), you will hack any dialog as badly as the cuts that have been made by the German classification board (alright they didn't cut the movie, but they made the suggestions on what had to be removed). Twists and story elements just don't work under that circumstances ... it's a shame for all those special effects that might have be better used on a better movie ...
