Droll comedy, but works better as a time capsule
The comedy part of the movie is rather forgetable with Bob throwing out one liners that are so dry and subtle that they just don't register as comedy today. I'm sure 50 years ago, the audience were probably howling with laughter.
The real reason to see the movie is the slice of 1960 life. The cars, the houses, shopping and the way people lived the suburban lifestyle 50 years ago. Today, we think mid-century retro is cool, but in this movie we get to see all in context. The grocery store scenes were my favorite visual.
