I watched it a few weeks ago on Netflix. It's gory, especially the first half of the movie where "One-Eye" is a captive and when he eventually breaks free of his bondage. Don't want to give too much away. It's worth watching at least once for the story. I, personally, didn't find it to be a movie worth watching over and over again. But, then again, with all the movies available on Netflix now, I hardly watch any movie twice... regardless of how good it is.
A very different movie than most are use to. It would be hard to recommend it without knowing someone liked watching such movies, but then it's so hard to describe that it's near impossible to predict if someone would like it.
