Actually the dork community says the science was pretty good.

And I enjoyed it. It’s nice to get some movies where none of the characters are @#$holes.

I haven't seen the movie but I read the book “The Martian.” The book explains the science in great detail. The whole narrative jumps from one problem—minor or major—to the next problem and how a solution is arrived at using very limited resources. It incorporates biology, chemistry, various fields of engineering, metallurgy, topographical navigation, etc.
