Everyone should be clear that we are still talking about high literature. The books are all very thin and quasi little "trashy books" with nuclear war scenario. But that's what makes the charm. Those looking for a similar scenario, and also something more sophisticated literary fare want, you should treat yourself Swan Song by Robert McCammon. In my opinion, the genre-Primus the apocalypse novels, The Stand by Stephen King, superior in many areas.
The Deathlands series, however, is just shallow entertainment for in between, will also no longer be.
