The best science fiction movie I’ve seen this decade. Most of the promotional stuff was not in the movie.
Follows the book—mostly. Good script; good cast; good effects. Looked as if it was filmed on mars, not in front of a blue screen.
This is real science fiction. All those others (Star Wars/Trek, Doctor Who, Marvel, etc.) are fantasy in a “scientific” or alternate universe setting.)
Matt Damon nailed Mark Watney.
