You're absolutely right. And the most frustrating thing about this is that there is absolutely no way whatsoever to prevent such movies from being unleashed.

How can someone come up with such a disturbing storyline, get funding for it (maybe it's his own money, who knows), find willing actors to act in it and all that jazz? It's a crime!!!

And the saddest thing, not forgetting disgutsing as well, is that there is a part 2.
