Is it time to shake up "American Idol" theme nights?

Last week, as ratings took another plunge, contestants mostly struggled with the songs of Frank Sinatra — a genre that surely didn't hold much appeal for younger viewers. It was a "death trap," claimed Lauren Valla, a 13-year-old member of our Readers Judges Panel.

Now, this week — in a rerun of last season — Jamie Foxx will mentor the four finalists in songs of the cinema. Ho hum.

Do we need new theme nights? Fewer of them? Is it even fair to force, say a folksy singer like Crystal Bowersox, to get glammed and do a Sinatra tune? We put the issue to our panel.
