Query: Well done adaptation.

Peter Telep has adapted a screenplay very well indeed. The book is gripping, and I read it very quickly. When I put it down, I returned quickly to finish the read. I almost wanted the character's peril to continue rather than have the conclusion arrive, because the time on Mars, and the solutions presented to the problems that crop up are really excellent. The science is good, and I will see the film, and hopefully enjoy it as much as the novel. If you don't like Christian spirituality mixed with your SF then be wary, but don't disregard the book because of it. It remains thoughtful and the religious parts were not overly objectionable to this non-believer.
