Playwright Theresa Rebeck, a master of barbed contemporary dialogue, conducts an interesting experiment in the Magic Theatre’s world premiere of What We’re Up Against.

Her Petri dish is a big-city architectural firm – all glass and metal in Skip Mercier’s sleek, mostly black, white and gray set. Her chosen bacteria: the architects, all of whom turn out to be antiseptic assholes.

To stir the chemical reactions, Rebeck introduces elements commonly found in the workplace: power plays, raging sexism, vaulting ambition, moronic behavior and that ever-powerful agent, greed.

The architects at this particular firm are mostly isolated from the outside world. We hear about some client interaction, but the focus of their activity is internal. There’s not talk of spouses, significant others, children, parents, pets, groceries or dry cleaning. This nearly two-hour, two-act drama (with some hearty if stinging comedy) has a sharp focus and that is unpleasant behavior from unpleasant people.
