Queer as Folk may be over the top for you, but it's pretty mainstream to the Gay Community.
Unlike "Will & Grace" (total stereotypes played out by straight actors), every gay person knows friends very much like every character on Queer as Folk.
That show has made Showtime profitable again.
When HBO got Sex in the City, The Soprannos, and Ozz, everybody started converting to HBO, and Showtime had nothing but old movies.
With Queer as Folk, Showtime is now back in the black and producing other specialty shows,
like "Dead like Me" and "Out of Order" (both great by the way).
The Gay market is a niche market, true, but with millions of watchers, a niche market can be quite profitable (as the "Fab 5" just proved on BRAVO).
I am the first to agree that many people live the lives of the guys in queer as folk. I just feel that it was a little over the top. Some episodes and some scenes were very exaggerated. The gay market is def a HUGE niche and hopefully soon the cable network that is being created by MTV and SHO will come out.
