Just got all of these on DVD and... its strange.
I remember the series fondly from my childhood but Filmation's reputation hasn't exactly bloomed over the years, what with their dire Apes, Tarzan, etc efforts not standing the test of time at all.
But, put this on, the grownup in me is sneering at the crude animation, the awful plots, the terrible voices and the insane decisions ("down" cries Supes as he goes to fly down) - and i still love it.
There's just something about these credits and the way they've gone for a 60's midlle-age look for the guy. Christopher Reeve will always be the best actor to play the Kryptonian but, to me, this is the comic version brought to life.
