Television has a problem. Too many of the fall season’s new programs — ABC’s “The Nine”and “Six Degrees,” CBS’s “Jericho (CBS),” NBC’s “Heroes,” etc. — have narratives that spread forever outward like Southern Californian tract housing marching toward the Mojave desert. Plots disappear inside so many subplots that to miss an episode is to risk rendering the entire viewing enterprise meaningless. (And that’s if the shows aren’t canceled.) Television used to be about relaxation, but teams of pop culture Tolstoys are starting to make it feel like homework. The TiVo runneth over.
