Shows don’t just waltz onto Broadway. They have to earn their place, which often happens in the smaller theaters sprinkled throughout the city, making them the best place to see edgier productions. The stars are just as big — Zachary Quinto is back onstage in the surrealist family drama Smokefall, while Joshua Jackson is a Harvard scholar in the political satire Smart People — and there is always a chance you’ll see next year’s big hit in Times Square — Hamilton took its first steps into the pages of history at the Public Theater. And during Off-Broadway Week, which begins today through Feb. 14, many productions are offering two-for-one tickets. We picked five shows that will entertain, intrigue and move you to tears.
