120 years after its Moscow premiere, Chekhov's Three Sisters is now for the first time staged at the National Theatre in Cluj-Napoca. The three sisters, daughters of a once-prominent general, Olga, Masha and Irina dream a dream of unattainable happiness, eternally projecting and postponing their desire of leaving the provincial town they live in and going back to the capital of Russia, their place of birth. If in the 19th century limitations were mostly geographical, technological, and social, not only psychological, nowadays the impossibility of personal fulfillment is heavily marked by psychological blocks. These are, however, essentially humane, and a constant presence in the history of humanity. What is preventing us from acknowledging happiness today? What dampens our spirits and diminishes our courage to leave behind the wrong choices and change for the best, optimistically moving forward? These are all open questions encircling Chekhov's characters, just like the walls of the vivarium which encloses them on stage.
