In 1910, renowned composer and conductor Gustav Mahler met with Sigmund Freud to discuss his troubled relationship with his young wife, Alma. This became the basis for Otho Eskin’s play “Final Analysis,” now playing at the Signature Theatre. Eskin eagerly builds on the real life meeting of great minds by including several other famous figures (from Josef Stalin to philosopher Ludwig Wittgenstein) who were also in Vienna around that time. The result is meant to be an exploration of the forces of love and hate in the world and what happens when conflicting worldviews clash. True, the characters rage, ache and exposit to one another in a variety of tones, but too often come off as rather lifeless and static.
