Chris hit it on the head. Pass the Buck is one of those shows I've found game show fans to either love or hate (You Don't Say is another such show). I happen to like it.
The conceit of playing hot potato with a list is fine. We can imagine it with things like "name a U.S. state" or "name a vegetable." But when you get into "name a beverage you wouldn't typically see in your lunchbox" and you watch the judge make one bad call, for or against, a large group of viewers are going to give up. The talking back at the screen turns from chastising the contestants to chastising the show. I also felt like players tried to push less-than-stellar answers with an air of "I do this all the time!" and that was a little annoying, too.
There are ways to ease the main game and endgame problems that we've discussed before. Use a "jury" like Scattergories in the main game. Canvass answers for the endgame (from a survey, or a handful of audience members), and take only some of the answers at random for the board.
Do those changes make it a long-running classic? Probably not. In the same space, it's more satisfying for viewers to match wits with a survey on Family Feud, and claim ownership over whatever "right" answer the stage contestants missed vs. having the 92nd thing that could have kept the game going on Pass the Buck.
