I just watched the whole thing a couple of days ago. It’s very disturbing but worth it. I don’t have a strong stomach for that kind of stuff at all but I made it through it. The skinned dog is definitely the worst part of the whole film in my opinion. I did have emotional outbursts for the rest of the day for seemingly silly things which I think was related to leftover sadness from the movie.

I think it is worth seeing, even though it is hard to watch. Also, turn the sound down in the bad parts – it helps.
