In Prospect Theater Company's ultra adorable, suitably tuneful and somewhat flat adaptation of F. Scott Fitzgerald's "This Side of Paradise," the social-climbing Scott (an ardent Matt Dengler) pursues a dangerous deb, Ginevra King (a pert Jessica Grov�). This courtship never generates much heat, so it's lucky that Cara Reichel's production steps lively and that Peter Mills's pastiche and Porter-esque tunes have jaunty rhythms and internal rhymes to spare (1:30).
