Summer Stock raises its degree of difficulty a bit with this show, which features tough stuff like synchronized jump rope scenes, onstage costume changes, live animals, and dozens of performers on the stage dancing and moving at the same time, but it also hedges its bets by putting on a show whose tone makes the ever-present sound problems and occasional prop malfunctions more forgivable. Bryant and Middleton, as the primary leads, are so easy to root for – and Fariss and Koudouris, as the villains, are so easy to root against – that spending too much energy worrying about those things seems like an exercise in joylessness. Who has time to care, when there are so many people having so much fun on the stage?
