If you loved Case Closed: The Crimson Love Letter, try LUPIN THE 3rd vs. CAT'S EYE
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Kobun Shizuno, and they sit in Action / Animation / Crime territory. If that's the register that drew you to Case Closed: The Crimson Love Letter, the second film will land in a comparable space — through a different lens.
What LUPIN THE 3rd vs. CAT'S EYE is
Lupin III gets into a paint-splattered fight. He competes with the Kisugi sisters for a triptych. It predictably gets chaotic.
