You dont often hear people praising 22-episode seasons, but they could allow some of Doctor Whos more complicated story arcs some room to breathe. Take the Masters return in 2007 or the bees disappearing leading to universal collapse in 2008. Both are no sooner set up and explained than theyre resolved via that deus ex machina from Richard Donners Superman movie. Ultimate foes and high stakes need more than two weeks to sink in, and American showrunners are less timid than either Davies or Moffat have been in stretching longer stories through the spines of their shows.
