what was the real reason why everyone hated elden ring bosses when the game first came out?

So i’ve been going back on older elden ring posts on this subreddit and surprisingly, I’ve noticed that a lot of people actually hated elden ring bosses and the dlc bosses when they initially came out. Most of the arguments were that there’s no punish windows and that the bosses were too artificially hard but I think it all boils down to people not wanting to LEARN the bosses. But if you do genuinely don’t like elden ring bosses, what are some of the reasons why?
