1: Is the game truly difficult? No. But it is challenging. Very challenging at some points. If you run in and die and die again until you don't die one time, guess what? It's because you learned how to fight that enemy, consciously or subconsciously. Actually having to learn how to fight an enemy = Challenge. (or in some cases, difficulty)
2: No story to speak of? Just because the story isn't obvious and literally thrown into your face like in Skyrim or other such games, doesn't mean it isn't there. Little npc's to have a worthwhile conversation with is part of that. Guess what? This world doesn't care about you. You're not seen as some magical hero and no one is blurting out their personal history just because you talked to them like in Skyrim.
3: The controls aren't hard. They're different so take some getting used to. But once you do, they work perfectly for the game. They might not work in other games, but in this one they fit.
OP's complaints are typical of a current-gen gamer, imo. People like him haven't actually played the oldschool games from the 80's and 90's where games were a lot more challenging/difficult than dark souls and where NOTHING AT ALL was told to you. Not even to the extend that dark souls tells you things. Heck, DS has a tutorial. Back in those days, as I recall, plenty of games didn't even have that. They just threw you right in. Even RPG's, yes.
