Just watch it. It's an origin story. Therefore it will be interesting. The animation is more appealing than most stuff I've seen... and there's 27 minustes of it. Also the voice acting is good. When it wants to be serious it succeeds. When it wants to be funny it succeeds. It's perfect, flawless, five stars. Watch it. 27 minutes. Also, jumpscare warning at 9:36.
