In the case of a revival, if the show heavily deviates from the original rules, it needs compelling enough gameplay to compensate.
For example, TPiR94 was a nice try, but they took out a major portion of the game. Yes, the pricing games are well-known, but they left out the reason it's called The Price Is Right. I'm not counting The Price WAS Right segments, although that was clever. I still enjoyed it as a 12-year-old.
The aesthetic feel usually doesn't have a negative effect, which is why I didn't mind Pyramid. However, what I DID mind was that Pyramid's execution was off. They could've played the damn game in my living room, and made the bathroom the Winner's Circle (OK, the toilet's too small of a circle). If it had been executed properly, I would've watched. No need for debate, it's been rehashed a million times.
The perfect example of changing the rules for no valid reason is Card Sharks 01. The genius that decided to go from two rows of five to one row of seven cards should be drawn and quartered...same goes for his or her supervisor who actually greenlighted the idea. Don't even get me started on the cheapskate Money Cards.
Also, don't try so hard to be edgy or hip. It is highly obnoxious (and I'm only 22), and it will make me turn the channel.
