Detective Conan OVA 04: Conan and Kid and Crystal Mother · review
Perfectly serviceable mystery story that's really a Kaito Kid story rather than a Detective Conan one. This predated Kid's anime series by several years, so this was his special outing at the time. That means it's the first animated appearance of his regular enemy, Snake (here, Jackal), who doesn't do much more than point a gun at a kid's head for some stakes-raising. The caper isn't complicated, the character motivations are basic, there's no interactions between Conan and Kid. If you want an extra 30 minutes with Kid and a few scenes with between Aoko and him, this delivers on that. Oh, also, the thing about thecat's eyes was a reference to a Lupin III Part I episode I watched recently. I got a kick out of that.
