I love it. Used to watch it as a kid until ~300th episode, but they never released the rest here. I started watching the original few years ago, but my pacing is rather slow as I'm still waaaay behind. Hopefully I'll catch the newest episode before it ends.
Don't know which case is my favorite, but I prefer episodes with guest characters, the police and the 1-2h specials. Nothing better than a 2 hours long Conan episode.
My favorite character is Haibara. Always was, always will.
