It'll happen, no doubt, but if the characters are at least likable - with some memorable banter - then I suspect the pedantry will be tempered somewhat. Then again I don't think it follows that a film be faulted too heavily for lacking scientific verisimilitude when it doesn't aim for such a thing as much as delivering thrills and artistic license, but hopefully some of The Martian spills over a little in terms of technical dialogue; the atmosphere of the planet, plant life, etc.
