Playwright David Lindsay-Abaire's beautiful Pulitzer Prize-winning play gets a genuinely heartfelt and at times moving production from Studio 300 Theatre. The cast has an easy, gentle approach to the material, which fits well with the comic air that runs over the surface of this bittersweet piece. It's an impressive feat for a new company taking on a story about how a couple and their family cope with grief and each other after losing their young son. Still, the actors have yet to fully mine the emotional depths Lindsay-Abaire wants his characters to go; sharp moments of pain and longing are quickly painted over with amusing ruminations on the curse of the Kennedys or punching people in bars. But even if this production isn't perfect, the humor and grace exhibited in it bodes well for Studio 300's future.
