I haven't watched any SS episodes, or parts thereof, since probably sometime during the late 1970s. If watched by kids of today, do you think the '69-'74 episodes continue to hold their original magic and appeal, that a present-day child would readily get in to, or do they now seem overly dated and clunky?

That is a good question. Whether it would appeal to today's children, it's hard to tell. Yes the clips look dated obviously, but I think it might appeal to some. I also have a Mister Rogers DVD set that covers from 1979-2000. Obviously I was older during those years, but they are fun to watch. I really want to see the shows from maybe 1968, when it premiered to the early 70's.

I was surprised years ago that little kids in my family were absolutely crazy about my DVD of Betty Boop cartoons from the early 1930s, and wanted to watch them over and over.
