PASADENA, Calif. -- ABC proved with "Scandal" that a TV show doesn't have to make a lick of sense to be popular. Now the network ups the ante with "Zero Hour," a valentine to even more bonkers programming.In the first "Zero Hour" episode (7 p.m. Thursday, KTVX Channel 4), there's a kidnapping, Nazis, Rosicrucians, an object hidden beneath a cathedral, a baby with crazy eyes and possibly clones of Anthony Edwards. Also: Clocks, lots of clocks that tick-tock ominously.None of this is to say that nuttiness can't be fun. It clearly can. But a program completely devoid of any hint of realism has to be approached differently.
