I had read about "Detective Conan" about a year prior to the show being released in the United States, and so when "Case Closed" began airing in May of 2004 I jumped at the opportunity to see this show. I was not disappointed.
This show is a welcome relief from the Scooby-Doo inspired cartoons (not to mention Scooby-Doo itself) that presented a "mystery" that a tree slug could solve in two minutes. The stories are well thought out, the solutions are NOT obvious but can be put together by an observant (and thinking) viewer, just as Conan does, and best of all the series does not insult the intelligence of its viewers: the show is entertaining without padding 3/4 or the episode with slapstick routines and mindless running from a person in a Halloween costume.
The show's premise is that little six-year-old Conan Edogawa is actually a 16-year-old detective prodigy. He was reduced to a grade school child when a mysterious would-be assassin gave him an experimental poison that (unknown to the poisoner) regressed the detective rather than killing him. In a bit of angst reminiscent of the early adventures of "Spider-Man", Conan makes a hard discovery: You can have the most brilliant detective mind in the world, but if you're six years old, all the police are going to tell you is, "BEAT IT, KID!" In spite of this hardship, little Conan finds ways of bringing the guilty parties to justice -- although all too often, someone else takes the credit for his deductions.
HIGHLY recommended.
