Classic Stage Company’s production of As You Like It is the latest act in Artistic Director John Doyle’s personal project to revivify the classics by whittling them down to their fundamentals. As with his CSC staging of John Weidman and Stephen Sondheim’s Pacific Overtures earlier this year, Doyle has slashed the text to its barest of bones and reduced scenic demands to a few plucky strokes. The approach neutered Pacific Overtures, but has made Shakespeare’s breeziest, most joyful romantic comedy even breezier.
