DEAL OR NO DEAL struck me as cheesy and unbelievable when it premeired several years ago. But it grew on me, as it did on everyone else. It's still sort of cheesy; the crying and sentimental "I need this money" talk gets old, and sometimes I wonder if the Banker is made of cardboard. But it's a whole lot of fun, and you end up rooting for the people on the show, whether they're country hicks, city slickers, or stay-at-home moms. Everyone comes to the show to win a million bucks, and it's fun to hope they do.
There is no sex outside of the tight dresses the case-holders wear. No violence or language. Almost all contestants start out with a selfless purpose, but many are caught up in the exhilarating pace of the game and they end up going home with $300 instead of a much higher amount (one must think it has something to do with greed).
There's really nothing innapropriate about the show, but I would suggest parental company for the commercials, which can get dirty. I imagine that's why the show got its TV-PG rating. Recommended.
