What do you think of videos of real people kicking the crap out of other people?

For me, it's entertaining as some of the fights' backstory can be very deep and suspenseful, but also to root for which one to come out of it alive. If there was a friend of family member involved, however, I'll be conflicted between revenge and entertainment since it won't be funny for me when someone I give a d*** about gets bloodied and battered.

I don't really care for violence for the sake of violence - not to mention the risks involved in setting up fights without proper equipment and referees.
