This movie is a collection of shorts, related by plot but unrelated in direction, voice acting, or artstyle. The end result is an interesting amalgam of artistic differences, but the story throughline is a solid genre narrative. I found most of the artstyles to be offputting, but if you like them you’ll enjoy this movie more than I did.
Closest comparison: It’s like the Animatrix by way of Batman: The Long Halloween.
Setting: Noir
Plot: Super Hero
Tone: Noir
