I felt the story line was a little weak on this OVA. It seemed to lack the well developed flair that most Detective Conan episodes have. The art was just like any other Detective Conan show. The music and sound were right on. The characters I had problems with. Personally I do not care for characters that copy other characters. Since the three children were basically knock offs of Ayumi, Mitsuhiko, and Genta I did like them at all. Their personalities were slightly different but it was clear they were suppose to be knock offs. The OVA was cute for a one time watch but thatis all it will get out of me.
