So far I've seen what's up on Netflix UK and a bunch of the first episodes, though I probably won't have to strength to marathon all 900 or so current eps anytime soon. If you like 1-2 ep length murder mysteries, it's a fairly decent watch in bursts.
You'd think all these kid friends of Conan would be permanently scarred with all the death happening around them (heck, the first episode literally has a guy's freshly severed head landing in front of them).
