Ronald D. Moore's reimagining of the 1978 Battlestar Galactica for Syfy is one of the great science fiction achievements in television history — a show that used the premise of humanity's survivors fleeing robot genocide across the galaxy to explore post-9/11 America's struggles with terrorism, torture, occupation, and the nature of humanity. The show's central question — 'what does it mean to be human when your enemies look exactly like you?' — generated four seasons of political and philosophical complexity that science fiction had rarely attempted on television. Its first two seasons in particular are as good as any drama of the prestige era.
