The main character resembles Clark Kent. He is a nerdy and kind guy at work but when no one is looking he turns into a super hero whose goal is to bring justice upon vilains (by killing tchem ofc). We don't get to know why is he that way, who exactly is he and what is his story. He definetly isn't a "generic good guy" but unfortunately he isn't memorable either.
When it comes to the art & music they are fairly ok for a 1991 anime. My only objection is that the music sometimes doesn't match the scenes.
And finally the most important aspect: "Why is YSJ not good as a horror?".
#1 There were only 3 scary scenes in the entire movie. It definetly is not enough for a horror that lasts 48 minutes.
#2 All of these scenes were really unrealistic. Maybe it's only me but i don't find magical books, weird deformed ghosts and birds which can cut you scary.
#3 The ending didn't leave me with any tention. When the story came to an end i felt as if nothing has happened. I think that if it was longer it might have been much better but it all happened to fast.
To conclude i don't recommend you YSJ unless you are an otaku hipster and want to show off your anime knowledge.
