As a native Russian who hasn't seen the series since childhood, I recently bought a DVD of all 18 episodes. I am happy to note that the cartoon remained exactly as I recall it - smart, funny, well animated, and even the Soviet-era themes felt fresh in that retro-modern way. I showed it to some of my friends, and they found it hilarious and not hard to understand at all. I admit that a bit of humour is always added through the lyrics of the pop-songs, which could be lost on a non-native speaker. The content of the series is also closer to the Tom and Jerry cartoons (Roadrunner??? Are you kidding me?), but smarter. I would highly recommend it to anyone as an example of fine and original film-making.
