Very holely when it comes to describing the future world. They cast is all clean and shiny. They have lovely, fitted clothes and nice boots (15 years after the factories closed); the militia have time to visit the gym as they are all muscly (yes, today's military do go to the gym, but that's because they have transport - future militia wouldn't have time for the gym, having to walk everywhere); no-one looks hungry or thin. Oh and oddly the wildlife (deers etc) seems to have survived nicely thank you - I would have thought they would have been hunted to extinction as people left the cities.
And then we get the script. "People who stayed in the cities all died". Where did they find the uncle...in the city, which was doing OK thank you. Monroe has been looking for the two brothers for 15 years, but he's obviously not looked very hard because one was within a couple of days' walk of the city they started from, and the other was...in the city.
Guns are amusing too. There is a constant running sub-plot about the lack of guns for the general population. The militia are the only ones allowed to have them. I can see how this might cause most Americans' teeth to start grinding "take away our guns...that's our civil liberties". To the majority of the other nations in the world, they wouldn't really understand how upsetting that is - they would probably shrug and say "law and order maintained in a world of anarchy by removing firearms...sensible idea." To carry forward modern views about weaponry, when everything else (computer programmers becoming farmers etc) has changed, seems stupid.
All that said, it's quite well put together, and the lead characters are strong and generally put in good performances. There's just enough plot (if you smile at the comments above) to keep you bumbling along.
