Dead Ringers seemed a lot like the show Saturday Night Live (SNL) in America. Those sketches were very funny, and the scrolling text was a nice touch. It was much funnier than the half-baked garbage that SNL has become (though in its Golden Days, SNL was the untouchable standard of comedy in America). Unfortunately, BBC America doesn't seem to air this show, but BBC and C4 have deals with other stations, so I can still watch Da Ali G Show and Extras in addition to the regular BBCA programming.
Personally, I've never found game shows interesting, and it is obvious that many of them are fraudulent. As such, I don't watch them (ever). The same goes for reality shows. So much American TV is garbage, it's a miracle that shows like Lost even exist.
