I've never watched any of those, sadly... But it's great to know there's another person who watches Conan. I thought I was the only one who's still interested and apreciative of the anime's story, since the anime series itself is old and all. Frankly, that's the only work of Hayao Miyazaki that I know of.
Future Boy Conan is one of those rare anime series that has a truly warm story, and I really enjoy watching it. Although, I've yet to finish watching the series.
