Maybe "instellar" is an overrated film: some wrote that was the best film they have seen, the most extraordinary film,etc !! It's a good story with some good dialogues, some nice photographies and some thinkings about the future of the humanity. I think that the success of this film is also due to the cast: Matthew McConaughey, Anne Hathaway, Michael Caine, Jessica Chastain and Matt Damon.
