Neither my wife or I have read the book, or even knew anything about it, so when we went to see the movie we had no expectations as to content. We did know from the ads and trailers that it was a "feel good" movie, and with Redford, Nolte, Steenburgen, and Thompson we felt it was something we would enjoy.
We were not disappointed. Even though some of the lines were familiar (e.g. Katz's comment on how he "wasted" 1/2 of his life), they were delivered so well that we laughed out loud.
For us, it was an entertaining 90 minutes. So, perhaps Steve's comment about the target audience is good.
Based on some of your comments I may even go out and buy the book to see what I missed.
