It seems to be the series that every one watches as they are getting into anime. And with this show, it really made the anime industry boom both in Japan and in the west. And with that boom, there were great improvements with animation techiques too.
The problem is that a lot of the newer fans are more attracted to things like the newer methods of animation and newer style of character designs. And if you stick any thing that is pre-1995 (with exception of Akira and Dragon Ball Z), they are just not going to be interested in it.
