I really like Sekiro, which is why is bums me out that most people think it's the worst one and FromSoft will probably never go back to it. Almost everything kinda boring and lame about Dark Souls was turned into an interesting game mechanic.

The stealth is a bit janky, but it's a lot more interesting parkouring around enemies to get to the boss without fighting them than it is just sprinting past them. Having a bunch of defensive options that you have to learn is way more interesting that just dodge rolling through everything with invincibility frames. If you want an "easy mode", instead of speccing into magic and spamming down enemies from far away you have to experiment with your ninja tools (or just look up their weakness lol).

Lastly, you can cut just about any boss fight in half if you learn how to get a stealth hit on them at the start. For a lot of the bosses it's possible to get a cheeky backstab that wasn't intended by the developers if you zip around them fast enough (just look up how speedrunners do it).
