Yeah I had the same thoughts too after completing it, it feels like there weren't really any more "over the top thrilling" moments/fights in ER than say DS3, but they were just spaced out way more. Some of the mini-bosses did give me some thrilling fights, like the Black Knife in a tiny chapel room was fun for me, but by the fifth time you're fighting the same mini-bosses in a different area it's very underwhelming lmao.
