I saw most of the Marvel cartoons of the 80s and 90s (also 60s spiderman was still on TV, I think just before Rawhide, so I also saw that), indeed it is the only reason I know anything of the characters (nobody I knew at any level of school in the UK read comics past the age of about 6, and even those were incredibly rare). Nothing I will go back for though. Batman TAS is something I can respect but no real desire to go back for. If I am allowed films then obviously it is going to be the Transformers film, saw a few of the TV shows but never took to them as well.
Trapdoor was awesome, still is actually.
Sharky and George
Earthworm Jim I imagine has not aged well (even my younger self found it a bit formulaic) but I will include it here, also the
German intro. I am not sure what I want to think about pirates of dark water other than to say I would like to see the story finished.
The Real Ghostbusters also wants to be here.
Far later I had a great fondness for Malo Korrigan. Starship Troopers animated was also something I really enjoyed, pity it was cancelled before it concluded. I used to get up really early to watch Medabots, shame they nerfed it for the second series. Insektors also gets to be thrown in here somewhere. Ulysses 31 used to be on really early and while I can't say I watched it a lot many of the themes kind of stuck with me. I imagine if I finished my list I would probably have enjoyed more cartoons originally made in the French language than Cyan which I find amusing.
Never really went in for turtles, he-man, thundercats or toy sellers not already mentioned. Going for the later US offerings then Dexter's Lab is good stuff and generally I consider Genndy Tartakovsky as one of the better cartoon makers to ever walk the earth. Pinky and the Brain also needs a nod and while it has its moments of brilliance the signal to noise to get them...
"younger age, but can be enjoyed by anyone" makes this a bit harder, mainly as we used to watch all sorts of things and outside of Heavy Metal (the more interesting side of anime had not yet made it to the UK) most animated things were for everybody. There was always some outright subversive/slipping it past the censors elements but South Park was really broke it out of that (though I imagine some will want to credit Beavis and Butt-head instead, never made as great an impact in the UK as few really had satellite/cable at the time, actually I don't know if cable was even installed by then). If I am including a couple of those then I will throw in Stressed Eric as many seem to have forgotten that which is a shame.
Beyond that there are many things I can remember well enough but have no great fondness for, or things I watched as I had siblings and knew something better would be on later and a fight over the channel would be more hassle than it was worth.
Seeing all this here though it turns out I really liked sci fi as a kid. Never really considered it before. Wonder if it resulted in me ending up the way I did or if that was determined earlier.
