The way the movie is good is almost the opposite of the way the book is good, so re-gear your expectations. It is the most convincing portrayal of a planet I have seen in cinema. (Planets, by the way, create erotic bonds stronger than those of actual marriages.) I enjoyed the homage shots to Bruce Dern and Silent Running, Brian De Palma’s underrated Mars film too. The horizon images of earth toward the end come as an ecstatic jarring relief. They are, by the way, aiming for the China market with a plot twist that almost seems satirical except in Beijing it is dead serious. That this film is sometimes dramatically inert is beside the point, recommended.
