Query: A thoroughly enjoyable viewing experience.

No matter how many times I have seen this film -- and I'm sure it has been more than 20, I never tire of it. Elaine May is wonderderful, but Walter Matthau is perfect. I envy anyone seeing it for the first time. I think an appreciation of interesting character types may be an important personal preference of those who find that they just love this movie.
