I watched it for the first time with a group of friends in the commons at my high school, and we were all laughing in a wtf kind of way. Like, it's a rainbow horse getting mutilated, it's just so out of place...
But if I had watched it by myself, I would have just kind of stared at the screen for a while. I don't usually like horror/gore/etc., especially if it's a person/character I really enjoy, so yea.
