Soviet cartoons are excellent!

I'm probably coming late to the party, but I am a complete fan of Soviet animation.

Due in great part to the lack of profit-driven interests, animation that was produced by the USSR is much more creative, diverse, and bold than (in my experience) mainstream American fare.  Innovative film-making techniques and the novel approach to children's entertainment makes the films produced by Soviet studios, like Soyuzmultfilm , an area definitely worth exploring.
