Exciting to watch- except when the calf reaches the end of his rope and about yanks its own head off.
I'm a wuss about things like that. I like bull fights too- until the matador pulls out his sword. (The matador is the guy wearing trousers that are so tight that after a few years he'll be singing soprano in the retired bull fighter's choir.)
I like the second better because I can see a face and the calf looks a bit more secure/under control. The horses head is also higher and in an overall better position.
