To put it in very simple terms - because it's well designed.
Most AAA games these days are a combination of poor design choices based on a checklist of what's popular in gaming and what sells. Dark Souls is an exception.
When you look at all those AAA games that are almost universally praised as best or among the best in their genre you'll see that it's largely for the same reason. For example Portal, Resident Evil 4 and Arkham Asylum. Superbly designed games. That's rare these days. As much as I think that The Witcher 3 is the best game ever made, I'm not blind to its obvious design flaws. They just don't bother me. But the existence of those design flaws is why there's a lot of people who just don't like the game.
