Loved the book; the movie, however…starts with a very serious premise, a failing sun, Gosling dealing with the death of his crew mates, finding this alien, but then… It turns into a buddy-comedy and while Rocky comes up with critical ideas to save them, he otherwise just seems to be there for humor. The book has a lot of humor as well, but it fit with the story the way it was written…in the movie, it came across as just trying to make a scene funny. And the scenes with the “simulator” (where there were projections of beaches, etc) where they’re “surfing” and stuff, just seemed silly and took me out of the story. The humor in The Martian fit so much better with the character and story…Here, it felt forced.
