If you come to New York for a weekend to see theater and you are in your forties or older, you might be thrilled to see there’s a new revival of a show of the 60s with one of the most famous titles of our time: Barefoot in the Park, a romantic comedy that was made into a hit movie with Robert Redford and Jane Fonda before either of them had become a public political cretin. I’ve seen it and I think you ought to save your money. Neil Simon’s play is sluggish and dull for the most part, and so is the production, despite its glittering star, Amanda Peet. The kooky young wife played by Peet seems like an entirely conventional pleasure-seeking New York twentysomething rather than a crazy wildflower, while the sober and responsible guy played by Redford in the movie seems far more neurotic and needy than she. I don’t remember a more disappointing night on the Rialto.
