For me, this movie was a no-go. In fact, it was difficult for me to watch. Not in the sense that it was boring, but rather I found it disturbing. If you are sensitive to gore and violence like I am, I would stray far from this movie.
I personally do not find peoples limbs getting ripped off funny. I actually felt quite uncomfortable sitting in the audience listening to people laugh while the actors were brutally mauled. I would have walked out if not for being with my family.
