people always say this but elden ring has like 8 or 9 unique boss fights total.
Graves is the problem in 90 percent of online discussion.
You mean 8 fights that don't get reused. Saying it as there are 8 unique fights in the whole game probably frames it incorrectly for most. It's not an invalid criticism but I think it's also an overexaggerated one. Saying there's a whole 8 unique boss fights is just silly because that makes it seem like you'll fight the same 8 bosses just with variations.
Just because one boss design got reused one time doesn't exclude it from being a different fight from the 8 you're mentioning.
EDIT: By the logic that Elden Ring has 8 unique bosses, you can argue that Sekiro has absolutely no unique bosses in it since it got updated. As far as unique bosses when you exclude the variants of them showing up in other phases or with a slightly different moveset, I've seen claims of 80 to 120 some for Elden Ring's different bosses. And the total number of bossfights in Elden Ring is 238 or at least that's what a quick google result is saying. So about a third (80x3=240 1/3x240=80) or a half (120x2=240 1/2x240=120, in case you need to see the numbers) of the bosses in the game are not variants of another boss. That's a fine thing to say is lackluster, but it's not 8/238. And the game is also a bit disappointing in some other regards, but it's also well made in many others. I don't think it's their best work but it's hard for me to say it's bad.
Graves is part of the autistic problem. It took me 200 hours to beat the game and I never whined about reusing content because the world was big enough to not be a big deal.
I played for like 200+ and for the entirety of the first playthrough I barely felt that way (and I saw probably about 70-80% of the game on that first play). On the subsequent playthroughs where I knew what I wanted only certain items for my build, I did purposely exclude going back to repetitive dungeons that wouldn't give me anything useful for that character. Then I finally got bored of the game because I explored all of it, beat it three times, and the PvP was (or still is) pretty lame. You either are a god and can win with any kit or you are a metaslave and use the same boring OP shit everyone else spams the second you load in. If you're not pretty damn good at the combat vs another real person, using subpar shit will just have you dying to a lot of cheesier builds or builds that have just about every tool under the sun with little apparent downside to the average player.
I'll play some more someday, likely post-DLC because that'll give me more singleplayer content and then I'll check out online again to see if it feels any better or not. I don't even need it to be super "balanced" I just don't like some of the OP builds and the playstyles they encourage (shield poke builds were just lame even if not too hard to counter).
