This is the first real Russian science fiction movie. I appreciated that it includes almost no ideological trash from the cold war, despite the time of its creation. The crew even includes one English speaking person, Mr. Kern. Mr. Kern is not as perfect as other members of the crew, but he is still a positive figure. What I liked was that this is real SF, and no mainstream movie with "magic" elements: there is space flight, there is an intelligent robot, there are fights with (quite funny) dinosaurs and pterodactyles, there are Venusians aliens and there is speculation about one solar race living on various planets but with common roots. It has all a SF fan can wish. (Except for time travelling and cyberpunk).
