A couple of no-spoiler nitpicks regarding The Martian (which, on the whole, I found quite good, so not ruined, but certainly a stand-out issue in such a decent representation)...
One: Says a technically-trained person, "Wind velocity is twenty-one point forty-one metres per second" (or very similar). I can't believe that any technically-trained person (in NASA, no less) would specify decimals in such a manner. And, if they do, I hope they're ashamed of themselves.
Two: The trajectories of the crew transitioning from the Hermes central corridor to the 'spoke' corridor down to the habitat appeared to consistently exhibit a curve. Treating it as a non-rotating frame of reference, the angled push-off of the central corridor would be straight (as a diagonal), and then upon entering the 'down-spoke' you contact the tube-wall before you start going straight down it. Treating it as a rotating frame of reference, you'd have to account for the Coriolis forces and aim ahead (to the turn-wise wall) and still wait until you contacted it before you'd curve in that direction. In neither case would you execute a graceful dive. (And I'd be doubtful about going in head-first, given you need to make sure you quickly tuck in to go feet-first down the ladder, however stylishly it seems they get to slid down to the apparently 1G end-node. You don't want to risk not getting a hold and being flung out head-first/downwards, by being propelled by the withershins edge of the spoke-tube. However, they've had months and months and months to get their space-legs. Even if they couldn't defy the laws of momentum.)
I'll avoid the spoilerish nitpicks, for now.
