By the time the title character takes to the skies in the Circa '21 Dinner Playhouse's Peter Pan, the effect, while wondrous, is also somewhat superfluous, since the presentation had already been airborne for a good 40 minutes beforehand, and will continue to be for the two hours that follow. If ever a production deserved to be called "ethereal," it's this one, but even that adjective doesn't suggest just how enthralling this Peter Pan truly is.
