Disappointing after reading the book

Rating: 6/10 (10 October 2015)

So much was left out from the book, as of course it had to be with the limited time frame of a film. But so much of the science that was so interesting to me was omitted, and a lot of unnecessary stuff that bored me was inserted to get butts in the seats. Not much to do for Matt Damon as Mark Watney, the stranded astronaut on Mars, so Hollywood did what it does so well, it added emotional scenes not in the book to get the heartstrings going, but not so much the brain. Some of it was too silly for credibility, from a science perspective.
Great visuals and NASA-type sets though, and I enjoyed those, even as the story was very lacking for those who read the book before.
