Only the second of the great Neil Simon's plays to be adapted for the screen, and, well, it shows. A year later he would pen the superlative, perhaps the best of his plays,
The Odd Couple (see the review in my thread Trollheart's Box Office) and you can see some of what would later make it into that classic in this movie, but it's kind of nascent? I was a little disappointed. The movie is funny, yes, but I found it quite flat, and Redford and Fonda somewhat wasted, especially Redford, who looks a little lost in it.
I guess you have to allow for it being an early try, moviewise, plus of course I don't know how many changes were made to the original script, but it wasn't quite as good as I had hoped. Still, it's telling that a movie released fifty years ago can still be enjoyed, give you a few laughs and more to the point, is still relevant today.
