This new series starring Skeet Ulrich (below) had me hooked with a single image: a kid looking off at a mushroom cloud. It was mythic, disturbing, beautiful, as if Andrew Wyeth painted the apocalypse. But the show is pretty dull. The people in a Kansas town witness the nuclear explosion, realize there were others and now have to deal with the fallout and maybe the end of civilization. Oh, is that all? Plenty of folks, Ulrich included, have secrets that may influence the drama, but mostly it feels like an instructional film about disaster preparedness.
