Chekhov's dramas are tragedies to those who regret love's frequently perverse timing and unrequitedness and comedies to others who find emotional paralysis, squandered talent, and psychic inertia cause for ridicule, not regret. Michael Menendian's staging of Jean-Claude van Itallie's adaptation of The Sea Gull, about two generations of artists misunderstanding one another, is determinedly tragicomic, honoring equally Chekhov's accurate diagnoses of human frailty and grasp of humorously wrongheaded good intentions. A true Chekhovian ensemble, the dreamers and dupers here deserve one another. And for Americans who think individual initiative can move mountains, this is a cautionary tale about people smart enough to recognize their losses but not strong enough to change them. --Lawrence Bommer a Through 5/27: Thu-Sat 8 PM, Sun 3 PM, Raven Theatre, 6157 N.
