There was a time before Jersey Shore, before Toddlers & Tiaras, before Dance Moms, when it seemed like unscripted television might be used for good. It goes all the way back to the time when the Louds were profiled on PBS's An American Family, but more recently when Pedro Zamora died of AIDS the day after the airing of his last episode of MTV's The Real World. Television is powerful, and while that's most often said with a shake of the head, now and then, it can be said with some satisfaction, and that's the way it feels to watch TLC's All-American Muslim.
