Coincidentally I just beat him a couple days ago, too! I'm playing Bloodborne for the first time after really enjoying Sekiro earlier in the year (never played any other From Software games), and I'm... well, enjoying most of it. I'm definitely not a fan of this Blood Vials system, and the long runs from Lamp to boss are really grating on me compared to Sekiro, but when I'm not trapped in the loop of spending a minute running to the boss and then dying immediately I can definitely see why people love it so much.
I just beat Vicar Amelia, so I'm exploring the area unlocked after her fight, and I think I still have a bunch to do in Old Yarnham that I might go back and clear up, too (I got around behind a certain fellow on a certain rooftop, but I haven't gone any further).
