One of the thrills of the movie is watching the improvisatory trial-and-error process as the dancers explore psychological themes, contorting their graceful, amazingly limber bodies into visual representations of relationships and emotional states.

While it's not a blistering look behind the scenes, Last Dance gives a fuller picture of the creative process than most others of its ilk.

The real highlight is watching the dancers as they progress from their first, tentative improvisations to the final, complex performance.

It's a rare window on an artistic collaboration.

An illuminating glimpse into what goes on in the dance studio.

Last Dance is riveting when it focuses on the challenges of crossing a generational divide --The movie loses steam toward the end.
