Amazingly, i got it. In the period immediately following WWII, eastern European graphics– especially in film and animation– were fraught with undirected angst, pessimism, bad translation, talentless (or at least misdirected) creators, and lousy production values. Sort of The Brothers Quay+Ingmar Bergman’s weirder brother.
This is more akin to Soviet-made cartoons. Czech cartoons had its own weirdness, although they wern’t as angular as portrayed here (the ones I’ve seen, at least). The Czech cartoons I’m mostly familiar with are Krtek the Mole series, which are actually pretty cute (those were kids stuff, so that’s probably the point).
Let me defend Gene Deitch a bit by saying that he is being unfairly linked to the “Tom and Jerry” shorts only. Check out his “Nudnik” shorts (a Czech-animated series financed by USA’s Paramount Pictures) or his Terrytoons stuff if you get a chance.
