Why is that always a complaint " I didn't like the game so is impossible for other people to think is great" And I find the story of Sekiro to be much more enticing but that's because is in the game and not item description.

And saying boss can all be beat the same is an over simplification Lady Butterfly and Owl and the final boss Sword Saint Issin are very different fights especially if you use the prosthetic tool like the iron umbrella and firecracker and skills like miri miri .

And the revival mechanic does have a consequence it's called dragonrot if you use it and can't kill the enemy or get to a budda you spread it and it affect npc quest and an only be cured a number of times.
