I have not seen this movie YET, it was recommended highly, but have ordered the DVD. The following review further inspired me to buy it, along with 14,816 others (that rated it 88 % "1" and "2". I am always looking for inspirational movies.
" This was my cure for cancer. No joke. After chemo, after radiation, there comes the anxiety of how to live "cancer free." When will it come back? Will my life every be the same? Will I ever be normal? If the Martian can live with all his uncertainty about survival, I sure can too! Didn't expect this movie to be life-changing or a cancer healing message, but maybe if you're struggling with any kind of anxiety, this movie and how its main character faces his problems head on, without worrying about when the next one will come, can be inspirational to you too"
