The last play I saw on this trip to Stratford, Ontario, was Anton Chekhov's Three Sisters. In the past six months I have also watched productions of The Seagull and The Cherry Orchard. But this show was the most satisfying of the trio. I think I liked the play itself better than the other two. And the cast in today's performance was terrific. Of the quartet of Chekhov's masterworks, I have only Uncle Vanya left to see now.
