Loved it. It's very much like Martian. It's definitely more fantastical. It's better written. (I could barely put it down.) The main character may be even more charismatic than Mark Watney.

I liked the Martian movie but for obvious reasons they cut some of the best parts of the story that revolved around mixing invisible gases under various pressures in various containers. Andy Weir has made the screenwriters' job only slightly easier this time with mixing invisible microbes in various containers. The science is once again at least 60% of the fun. But the other 40% is still great stuff. I'm sure the movie will be a blast no matter what is omitted.
