Here is a sampling of what they had to say:
Charles Isherwood of The New York Times: "The play's wide focus may have something to do with its frustratingly unrealized quality. The play's temporal and dramatic scope is not matched by depth of feeling or nuanced characterization. Mr. Baitz's writing is, as always, often fiercely eloquent, but even when they are passionately debating the ethics of love, moneymaking and the elusive matter of happiness, his characters retain a hollow, manufactured quality… There are far too many unsmooth transitions and unilluminated relationships in The Paris Letter, despite director Michael Morris's largely skillful work… Despite Mr. Rifkin's cool, compelling performance, Sandy is a cipher, a victim of Mr. Baitz's tendency to moralize."
Don Shirley of The Los Angeles Times: "More than any other Baitz play seen in Los Angeles, this one fully fleshes out the playwright's thoughts. Staged by Michael Morris at the Kirk Douglas Theatre in Culver City, The Paris Letter is Baitz at his best. It's about 10 times more engaging than Ten Unknowns… With The Paris Letter, Baitz overcomes his tendency to step on the brakes too soon. This is a big play, with three acts and nearly three hours, covering four decades with a fragmented chronology that might momentarily confuse. But this is one of those occasions when more is more--nothing seems repetitive or unduly discursive."
