With apologies to "Lois and Clark," "Smallville" remains the definitive TV adaptation of Superman, partly because the writers made efforts to integrate other stars from the DC Universe into plot-lines. Case in point. Justin Hartley's Green Arrow, who blew into town in season six and quickly became an anti-hero foil to the blandly virtuous Clark Kent. Not only that, but he briefly managed to wrest Lois Lane (Kristin Kreuk) from her Krypton-powered beloved -- no mean feat.
