“Grey’s Anatomy”, appears on DVD in 1.78:1 anamorphic widescreen, matching the dimensions of the show’s high definition broadcasts. “Grey’s” resembles a feature film creation with its visual flair and like its cinematic brethren; it comes to DVD boasting visuals with nary a flaw in sight. Grey’s Anatomy summons a color palette of its own, favoring whites and light colors rather than the light/dark contrasts of “E.R.”
