For me, having less commercial time and more GAME time would bring me back to watching. Some seem to love Drew, some seem to hate him, I rather enjoy him for the most part. There were days when Barker would grate on my nerves too. Comparitively speaking, Drew's still a "babe in the woods" after 4 years on the show. I would love to see more time available for more involved games to be played. Now they play 3 or 4 quicky games, and most of the quicky games are for just 1 prize anymore.
Another would be to bring back pricing games that require some thinking & strategy (Hit Me, Mystery Price, Super Saver, Give or Keep, Check Game) just to name a few.
With budgets being as they are, and so many forced losses it seems, the show is rather unbearable to endure for very long. I'm almost to the point that I'd rather the show save money and air just 2 new episodes per week (Monday & Friday) and show reruns the other 3 days...
