It's impossible not to enjoy the Food Network show "Unwrapped." Its appeal, though transparent, is compelling: who couldn't be amazed at the sight of 10,000 Twinkies simultaneously being filled with cream as they proceed down massive conveyor belts and other industrial food preparation infrastructure?

Almost nobody, apparently: this show is now on every single night at 11 p.m. It will be interesting to see whether the formula becomes old from oversaturation. This should be called the "Behind the Music" phenomenon, named after the rockumentary series that made stories of fame, decline and subsequent redemption (with a new or forthcoming album) available on VH1 twenty-four hours a day.

"Unwrapped" may sustain its popularity, but if doesn't, nobody should be surprised.
