So again: for who is this being made?
This was made for the producers in an attempt to increase their profile so they could make bigger and better (sic) productions. The producers stated as much in an early interview.
To gain attention the producers tried to challenge a few basic human traits as fiercely as possible (survival, pain etc.) in to become notorious.
I haven't watched it, so I am speaking based only on a couple of reviews. I believe such movies do not offer me anything I need or want and I do not feel I must watch it to make that decision. I am happy to risk not seeing the movie if I am incorrect!
A follow on question would be: What kind of people enjoy or gain value watching these sort of movies?
