Watching four people try to practice "the art of coexistence," as the playwright puts it, is entertaining but ultimately depressing in Yasmina Reza's God of Carnage at Marin Theatre Company. One of the hottest plays in recent memory, Carnage is the perfect storm of contemporary drama. It has one set, four actors and that perfect blend of satirically repulsive comedy and apparent moral heft. Oh, and it has impressive vomit special effects and that most satisfying of dramatic dénouements, the destruction of a mobile phone.

What it doesn't have – not even in this brilliantly produced MTC version – is a satisfying reason for being.
