I think it's safe to describe "Queer As Folk" as one of the most important LGBT TV shows in the history of television. While the original UK series only lasted two seasons, the US version lasted five seasons. The show was renowned for it's depiction of sex and drug use and controversial story lines. It was incredibly well made show - definitely a MUST watch!!
