Game Shows would be cool, but it just occurred to me that it's a bit similar to board games. I'm a stickler for variety. Whatever wins, I hope it is music-based.
Also, I watched Camelot recently. Not a bad movie, but it goes a bit long. It sort of slows down after the joust and doesn't really pick up until Mordred shows up. Some of the songs are a bit long and repetitive, but I think that's sort of intentional, in the same way that dance songs go really long: it's supposed to swallow you up and get you lost in the mood. Didn't quite work for me, but still enjoyable.
