It's pretty effing gruesome.
I don't agree with the animal rights people, but bull"fighting" is awful. If you haven't seen a bullfight, only seen videos of a matador killing a bull, you should know that the matador doesn't even walk on the field until the bull is completely exhausted, blinded, and near death from the shock and blood-loss of being stabbed dozens of times, and the matador's job is to finish off the bull with as much showboating as possible.
Before that the bull has been tortured for half an hour to an hour. It's not a fight in any meaningful sense of the word.
