Someone posted, there isn't one documented wolf attack in history. You need to do some research. Many documented attacks plus 5 fatal attacks since 1989.
Most recent attack, a 14 yr old boy in MN. He survived. A woman was killed by 2 wolves just a few yrs ago in Alaska.
Just the lack of sunshine for so long will cause great psychological stress.
Those that give it low ratings probably want a somewhat scripted/planned show like Survivor or Amazing Race.
Of course its a slow paced show, no host to try and make it interesting, no competition for food rewards, no hype. It is just men left alone to record their daily struggles.
