It's taken me 30 years to finally watch Detective Conan.

Shinichi Kudo is a high school detective when one day he is poisoned trying to stop the mysterious black organization, instead of dying, Shinichi is shrunk into a child form, now living with Ran Mori and detective Kogoro Mori, he takes on the name Conan Edogawa, with gadgets in hand ranging from powered soccer balls, tranquilizer darts, voice changing bow ties and a rocket skateboard along with a willing group of child detectives, Conan sets out to solve mysteries to eventually lead back to the Black Organization to one day reclaim his previous form, although Kogoro seems to get all the credit because Conan is still stuck as a kid.
Seems like Detective shows always get the long runner treatment, Detective Conan posseses the same spirit as the likes of Doraemon but has enough grit to not alienate itself from an older audience, it's got a healthy load of action and each episode and movie draws well from a strong cast and strong writing, it does suffer from early era dubbing and it has the Lupin the 3rd problem of not having much to distinguish itself between it's episodes and movies, even turning up in Detective Precure could be considered a standard episode for Conan.
Final Verdict: Detective Conan is a decent watch with 30 years worth of content to keep you entertained for months just don't expect the ground to break.
