Kidnap and torture isn't really horror to me. :/, primary reason why the Hostel movies didn't appeal to me much. There's nothing terrifying about watching someone get tortured or kidnapped. The only case in which I can see something like that being terrifying is if your the person getting abducted and/or tortured. Or if it's a loved one.
But that's not the case. Therefore, that didn't really appeal to my tastes in terms of what "horror" is.
