Melissa McBain's drama Altar Call, currently playing at Playcrafters' Barn Theatre, is beautifully unresolved. There are many fine elements in this production - along with some not-so-fine ones - yet I was impressed by McBain's willingness to let the drama linger after its close. She introduces potentially volatile subject matter such as adultery, homosexuality, and the dogmatic elements of scripture, yet doesn't attempt to provide easy answers to the play's complexities.
