Paranoia Agent (2004)

13 episodes. A boy on golden inline skates is attacking people around Musashino with a golden baseball bat, and nobody can describe his face. This is the only TV series Satoshi Kon directed, and it plays like his films stretched across a satirical crime story. Each episode hands the camera to a different victim or bystander, so the show keeps changing shape, from police procedural to dark comedy to something stranger. Keep the episodes in order: what looks like a run of oddball detours all feeds into the finale.
