The new Card Sharks will reportedly differ a great deal from the classic CS
reruns we see on GSN, and will get old faster than the reruns do.
Ergo (hopefully) being cancelled quicker (if it's as bad as everyone thinks
it is)
I do not have GSN, however I do have two episodes from 1979. And I have
watched them both a dozen times each, and I still love watching them. It's
just the way the show is.
