Thanks to Pavel’s initiative, I watched Кин-Дза-Дза (imdb) again. It is an outstanding movie! In order to really appreciate it, I had to see it twice. One of the themes is the Soviet Perestroika, but a lot of other themes are treated: friendship, social & cultural rituals, racism, bureaucracy, communication and many others. Moreover, the film is very sound from a Sci-Fi perspective: The machines look a bit old-fashioned, but there is nothing that isn’t convincing. The behavior of the aliens seems to be odd at first sight, but after some time (and esp. if you watch the film more than once) it has a certain logic. The dialogues are very funny. The Moscovites’ strategies how to tackle with the aliens and their culture are quite interesting.
