Moss Hart & George S. Kaufman's 1938 comedy You Can't Take It with You is so sturdy and reliably entertaining that it doesn't take much more than a mediocre version of it to make audiences happy. The current production at the Richmond Hill Barn Theatre is significantly better than mediocre - vibrantly played and almost consistently pleasurable - but what's completely surprising is the cleverness and skill behind Vicki Deusinger's staging of it.
