Oddly enough, I had the same experience with Dark Souls! It took dozens of hours on both 1 and 3 before it actually finally "clicked" for me, but now I love them (even 2) and do replays not infrequently (thinking of doing another one soon, actually). I am basically entirely a singleplayer gamer, so we have opposite experiences there, I don't think I've ever enjoyed a multiplayer game (well, unless you count Untitled Goose Game which I played through with my sister, you can cause so much extra havoc with two geese! Very fun!)
