I found this a really good way to cure the curiosity of a watcher who just finished the main episodes. It was a 13 minute long episode, and I liked it that way. I would really re watch this since it was just an episode but based on how this cured my eagerness and only 13 min long i cant really judge the music etc so as u can see i gave them all 10/10. I felt satisfied after watching it and there really isnt a point to why you shouldnt. Its short so it wont take much time, and just gives you more details about what happened in the end.

Sorry for the grammar/spelling mistakes.
