Christina Davis

It would be unforgivable if a show called Sex failed to be funny, given the range of available material. Davis’ set avoids well-worn jokes, managing to be both surprising and intelligent. But Sex ultimately suffers from a somewhat disjointed delivery and a tendency to undersell her punchlines, muttering them dismissively before the audience has a chance to laugh.
