Okay, my Thundercats love is not shared by many of those who should have the nostalgia value for it, but I think some 80s cartoons can hold their own. Thundercats and Bravestarr both had good introduction episodes (both before the "morals must be spelt out for kids" rules came in), but were both action sci-fi fantasy cartoons and I'm not sure that's your thing. I'd be interested to know what you think of Ewoks, which is also a sci-fi fantasy thing as well as a Star Wars spin-off, but it's set in a little village on an alien world (a moon of Endor) and only 1 ep has any overlap with the film's main setting, so it's fine as a standalone thing. I'd say it's like MLP G1 but with better-defined characters. It has some truly surreal moments and isn't as chipper and witty as today's cartoons, but is cuddly at its core.
...Though maybe more monsters and action than the slice of life and character-interaction I think you may lean towards. Hm. S2 was toned down for a younger audience, though it still had some creepy moments and focused more on the village kids (gah). Maybe not that then!
But I still think a lot of 80s cartoons (at least parts of them) could entertain today's audience just as well.
>>Ha, true! It's leaked into other media forms too, with some films, series, and card game sets having the colour sucked out for an "edgy"/"serious" look. It's a bore.
