Grim and disturbing but there must be something about it as I want to see the ending.
Basic plot is based around some strange reality show not unlike Big Brother. 8 participants earn money but things aren't a bed of roses.
It's a violent show and to the point where I almost stopped watching. Not for the faint hearted to say the least.
I noticed a few plot holes concerning the rules of the "game" but they may be explained in the last episode which I'm yet to watch.
