NO MATTER HOW HARD WE TRY is staged exactly where it should be. Wedged behind a tiny door at the end of a dark alleyway, Trap Door Theatre’s space perfectly suits this absurd portrait of drab and depressing life in Poland after World War II. Joanna Iwanicka’s set, a single dull, monochromatic room flanked by electric blue refuse (think Sin City, but five feet away from you) spills ever so slightly into the audience. You’re simultaneously in the room and observing it. A tiny, glowing TV screen sitting downstage center faces the stage, muddling the notion of who is watching whom.
