Anyone who thinks that any 100+ episode animes are instant crap, then i suggest Detective Conan.
Though i'd only suggest it if you love Detective Mysteries as much as I do, and i LOVE detective mysteries.
Also, one thing to note about Detective Conan, even if you don't like Detective Mysteries, it WILL make you laugh hysterically. The funny parts are fantastic, much better than other shows dedicated purely to comedy.
Whats so funny? the engrish. It's not that noticeable, seeing as their aren't alot of english speaking characters, but when it does show up, its great. Characters that are supposedly American can only speak engrish, while being able to speak japanese perfectly.
The single most egregious example is an episode that takes place in NEW YORK CITY, and the only person that speaks english is a policeman, but only for an instant, and even then it's broken english. Everyone else in New York City, of course, speaks and understands fluent japanese for no apparent reason.
As far as i've seen (and i'm around episode 250), only one episode starred characters that spoke natural sounding, fluent english.
That may sound bad, but it's a hilarious kind of bad between all the awesome Detective work. My favorite is the Conversation between an English Teacher (good english) and Inspector Megura (bad english).

"Policeman!"
