Probably, though I did beat and enjoy the first three games in the Dark Souls series (if you include Demon's Souls) before I got tired of it, despite having to iterate on some bosses. There are a few saving graces that make it tolerable: effective options for cheesing, being able to grind XP/gear to make it easier, mandatory downtime between fights that punishes trying to brute force practice them, the option to give up for a while and go explore somewhere else, the presence of more dynamics to fights to optimize than correctly reacting to patterns to the point where you can remain mostly ignorant of them and still win another way. Playing DS3 I got the feeling that maybe the issue was getting worse and I was kind of burned out on the gameplay overall so I dropped it.

I would cite Super Meat Boy as a more pure example of the problem I'm talking about, that game left me feeling brain fried and like I hadn't learned or accomplished anything.

I'd like to direct your attention to the prior games in the series we're discussing, which have no such issues despite being made by Fromsoft. This "hurr durr issa Fromsoft boss get used to it" schtick is fucking insufferable and ignores the 15 years of history that company had before making those godawful Dark Souls games.
