I have to say the Dark Souls series may a bit overrated as well.
It's my favorite franchise of the last two generations, but they're buggy, have bad performance, and handle side quests in a ridiculous way where it's way too easy to screw up quest lines and cutting the player out of content until they start a new game.
Honestly, the fact that, despite so many problems, Dark Souls is still one of the best series ever speaks volumes about its appeal.
