Sometimes someone will be really really super into something. Call it what you will, but I find that passion captivating. These are works that are both good and passionately about a thing, I guess. Most people might find some of them frustrating due to an overfocus on the core concept of the story and diminishing attention on like, human relationships and stuff. I enjoyed these anyway. Strong overlap with sports.
