I love Bloodborne and it's my proudest platinum trophy.
That said, Resetera is obsessed with the game so, take the feedback from here with a grain of salt... the game is niche. The game might not "click" with you, and that's fine. I've tried to get people into the game and sadly it doesn't click as it did with me. I think my one and only recommendation is that the game wants you to think and take your time. Never fight more than 2 enemies at once and always retreat if you need to and never rush into the unknown. Try to prepare, take your time, and approach the battles on your terms. The game has also tons of horror influences, if you like horror, stick with it because it has some great moments. But again, if you prefer to feel omega powerful and destroy crowds of enemies, this game isn't for you.
The other criticism is the "grind" for healing items. I never had that issue. I think I found a route that yielded plenty of blood vials and just ran through there a couple times, but it wasn't bad and it didn't bother me. I think farming items or XP is such an essential gaming trope that it didn't feel weird or forced. But if you actively use tons of blood vials and never go out of your way to grab some, then sure, you'll run out at some point. The criticism comes, I think, from the comparison with Dark Souls, which refuels your healing items when you rest. But this game, as similar as it is to Dark Souls, it is also it's own thing and I think it's better for it. If you enjoy it, the healing items system in Demon's Souls is similar (herbs instead of vials).
Lastly, the game is both, one of the most beautiful games ever made and has horrible performance. I think on Pro it runs better and I think with Beast mode the frame pacing is near perfect. But you'll see the frame rate chug at times in base PS4. The faces of your character is very ugly, but you'll probably get a hat or mask early and never see your face again lol. The environments are very dense with detail looks amazing.
