While there aren't any talking animals, big lavish song production numbers, or villians with half white / half black hair ... it does have 1 thing ... realistic people acting normally in a strange circumstance, and Walt Roy did in their eras with the studio. If you thought think "The Castaways" or "The Island At The Top Of The World" weren't identical, or you hold them to a higher authority than Atlantis, then your idealism is just as whacked as keeping your kids up till midnight to watch a friggin' cartoon.
