The Soviet mini-series that adapted Jules Verne's "The Children of Captain Grant" [1] is really nice, it's from the mid-'80s, a time that supposedly was bleak because of Chernobyl and the post-Andropov and post-Chernenko years, but nevertheless to kid me the TV series seemed full of optimism and of endless opportunities and marvels. That's from where I got the nickname I use on this website, too.
