I saw this film the other night on television and thoroughly enjoyed it. I doubt that anyone would claim that it is a major piece of art, but it gave me a good feeling. True, some parts of it were perfunctory and could have been expanded, but I'm not complaining.
I found a very interesting interview with director Rob Reiner, which explains all kinds of things about the film. The budget for the entire film was five million dollars (Julia Roberts gets/got 20 million per film!) and it was shot over only 25 days.
