Daughters of the Sexual Revolution: The Untold Story of the Dallas Cowboys Cheerleaders

Mostly, this is a whirlwind trip through the origins of a phenomenon, with an eye toward explaining how America could find these ladies at once sexy and wholesome.

The tone is unabashedly partial, yet the women are such entertaining company it's hard to mind.

An engaging, once-over-lightly documentary that takes you back to the moment when women, in a public way, were throwing off the last shackles of having to behave themselves.

A truly engrossing film, one that balances the big picture and the small one.
