I can't believe I'm doing this, but...
I'm going to defend card sharks 2001.
Is it a great game? No. Did it have squandered potential? Yes. Bullard deserved better. As did tami Anderson. The set was nice. The theme was nice. The payout potential was pretty good too.
Everything about the format has been stated above though. What they should have done? Two contestants, survey questions, change of cards with clip chips,money cards stays the same.
But here's the defense: remember back then everything- programming, movies, and more had to have an "edge" to get put on the air. Every show that came out for those few years had to have a "millennium or edgy" change. Feud dropped the Whitmans sampler look (and early promo images for andersons version showed it may have gone for an updated look originally) and tried to "speed up" the game with the four rounds rule. Match game and LMAD went crass,but it wasn't needed. Pyramid went technologically sleek and tried to speed up the game. TTTT started off like the original but changed to a springer-lite, rowdy form in season 2. PYL went dark (honestly this is probably the best of the updated shows from that era) and added the double whammys. Back then I don't think a shot by shot, classic remake of card sharks, or other game shows would have even sold. (Note: I wonder what the Gordon Elliot LMAD was going for- the few images out made it look rather....classy).
It didn't seem like the lessons were learned until around 2007 or so, when temptation flopped. LMAD came back later very similar to the original,but less with shopping games and more comedy bits that actually works. Price stuck to its roots post host change and didn't do an American idol style revamp. Pyramid put out several pilots that looked like the good updates to the 80s version, we got a cable version that was decent update to the show (and IMHO should have lasted longer-but I'm gladly didn't) and a current version that is one of the best shows In years; Match game came back slightly dirtier and a Little too polished, but probably the best update since the 70s; Feud went through a period that did more callbacks to its past with ohurley, but kept many classic elements in its syndicated run and celebrity seasons...even the jokers wild is a pretty classic show in its own right!
If card sharks were brought back now, I bet it would be done right.
