I was pleasantly surprised and pleased with the introductory speech by director Nolan. This even rose my expectations. You are slowly introduced to the world not so convenient for humanity anymore. What to do ? Explore the space and search for new place to live. But it is not that easy as it seems and appears to be one way journey. This is thrilling, emotional and exploratory sci-fi. Scenes made with analog camera are looking great at imax screen. Even story seems good until last 20 minutes of the movie. There come irrationalities and not so interesting conclusion. Overall good movie but with disappointing ending.
