I'll give you Godskin Duo. I didn't have any issue with the other bosses though. Maliketh in particular is fucking badass, no idea what your issue is with that one. And even if Elden Beast is on the annoying side, I enjoyed the spectacle of it.

I would also agree the game in general is maybe too big, but the boss repetition didn't bug me too much. Not every catacomb needs a unique fight after all.

The flaws still don't detract from the fact that Elden Ring absorbed me in a way that very few games these days do. Compared to other From games, I'd personally put it above DS2 and DS3, at the very least.
