I suppose we're lucky that this is a "season one" DVD and not a "complete series" set. The nut campaign aimed at CBS worked, and the second season of Jericho will start in a few months. It's only going to be seven episodes long, and then they'll look at those ratings and see if it warrants more episodes.
In the meantime, we have this season one set. You either like the show or you don't, which will help you decide whether you will want the DVD or not. And if you buy it, you're interested in the extras, and on this set they're actually pretty good.
