I have two words for you: The Office. And one more: Extras. Both of Ricky Gervais’ original British TV series ran for two six-episode seasons (followed by a special). [...] The British seem to do that with regularity: create a series meant to run for a single season of episodes. Period. Think about Prime Suspect, for example, the incredibly complex and compelling show in which Helen Mirren played a police inspector battling the old-boy network as well as her own personal demons. It ran as a limited series in 1991 – and, yes, it came back six more times (Prime Suspect: The Final Act aired in 2006), but never two seasons in a row. And even then, each series rarely ran for more than four hours – total. It only seemed to resurface when they’d fashioned a plot that was worthy of DCI Jane Tennison’s time – and ours.And yes again: We know the networks' economic imperatives require beating things like Lost and Heroes to death. But! When they decide to get as serious as the rest of us, we're in — just as long as nobody touches Tyler Perry's House of Payne. We really do need something to hold us over in those three-month gaps between Madea movies.
