I don’t blame you, but if you ever feel up to it, I highly recommend giving it another go. It’s very different from other souls games as I’m sure you already know. I say that though only having played Elden Ring before Sekiro, so I’m mostly going off that.
For me, once it clicked how important deflecting is and how not useful dodging is (most of the time), I was having so much fun. Certain bosses were extremely annoying at first, but almost all of them felt so fun once I figured out their movesets (another super important thing I had to realize). There are two bosses though that I am fully okay with never trying again. One of them there’s a notorious cheese method though, so on my NG runs I did that just to get the extra attack power. The other one isn’t cheeseable, but both of these that I’m talking about are optional unless you’re going for trophies.
The game turned from me not having fun into probably in my top 10 games I’ve ever played. The feeling of finally understanding certain bosses was pure elation. When I finally popped the last trophy for Elden Ring, I was kinda happy to be done with it. With Sekiro, I wanted to do another run just to see how much quicker and better it went.
I also very much appreciate not having to worry about a whole ass build, those options kinda overwhelmed me in Elden Ring and is a big reason I haven’t tried the other souls games. But I know a lot of people prefer having those builds.
