That's not enough to replicate the success of 'All the Way,' which won the Tony Award for best play. Mr. Cranston, whose portrayal of L.B.J. won a Tony Award as well, could carry that story, essentially a comedy, on pure skill and charisma. 'The Great Society,' a tragedy, needs more than that but instead gets less. It's bad enough that Johnson is so two-dimensional; the supporting characters have it worse. Their traits are parceled out on a one-per-customer basis: Humphrey's a patsy, King a worrier, Carmichael a hothead and Wallace a weasel.
