You will never see another Electra like Marya Sea Kaminski's Electra. There's not much plot to this version of the Greek ur-Hamlet (a child laments a murdered father and rages against the mother who married his killer), but it takes uncommon guts to digest Kaminski's searing performance. She mourns, yowls, pities, self-pities, and suffers through all the other difficult emotions so hard you'll want to take her home, wrap her in a blanket, and feed her a bowl of soup. The other actors do not—cannot—match the crucible of Kaminksi's performance. But they don't have to. She is all you need.
