Good man versus nature (twisted nature) setup here, with the payoff being that even in these extreme circumstances, human nature is still our biggest threat. It's handled reasonably well, if not in scope, then in action, though it treads very popular ground.

The simplicity of the wide open countryside after a zombie apocalypse isn't something we've really seen on screen before and it could be very cinematic. Throw in a couple of desperate travelers who don't know each other, forced to work together and it has all the cohesive pieces of a movie.

Another pass that turns Hudson and Clint's early back and forth into more conflict filled and goal oriented action may keep the first half moving and more fully inform their later actions as they find themselves relying on each other more and more.
