A brilliant film that helped define a genre

The story-telling is good with flashbacks.The film is both funny and heartbreaking. You smile in a scene and get a soulcrushing revelation in the next.

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
