Many of the sorter season dramas on the cable networks are pretty good.
They show up at different times during the year:
Burn Notice [getting somewhat stale—it has been on for several years]
Flashpoint (ION TV)
Copper just concluded season 1 on BBCAmerica
Hell on Wheels (AMC)
Most of those show up in reruns and marathons at various times.
Funny I see that about White Collar (which hasn’t been on as long) more than Burn Notice.
