This movie is full of small fascinating details for fans of space. And it is one of the few realistic sci-fi movies that are not going into full on cyberpunk. And i am sure this is the first movie in this century with first contact being a real problem to solve and not just shorthanded to move the story faster

And of cource, i miss seeing competent people saving the world

P.S. This is somehow third time this week i hear about Tau-Ceti system, it seems like a neat place
