I wouldn't call Headless Bloodletting Beast a relaxing jaunt and the last one can be a bit of a pain if you don't keep her clones down to a minimum. I once got mobbed by them at the end of the fight once and got killed.
I love Yharnam, one of my favorite bosses in the game. Bosses like Bloodletting and Loran Darkbeast are just annoying because you can't see them half the time. It's the reason why I think Gerhman, Gascoigne, Yharnam, and Logarius are the best bosses in the game - they don't feel like a crapshoot due to the camera.
