The movie Requiem for a Dream is, to me, a perfect example of a high quality movie that I will not watch twice.
The acting, directing, cinematography, pacing, and sound design are all excellent. However, the film is such a grueling emotional experience, I don't foresee myself sitting down with it again.
Contrast that to, say, Airplane. It's a good movie. Funny. If I'm bored in a hotel room, I'll watch it again. However, it is emphatically not a "great film."
Fair point, I asked that myself. See ErrantX's answer[1] which IMO totally makes sense:
> Why would I care about rewatchability?
Speaking as a film buff; this is actually quite a good guide to the sort of movie it is (when combined with quality). If lots of people mark it good quality, but wouldn't watch it again, that implies that you have to be in the right mood for it.
If people mark rewatchability high, even if the quality rating varies, you know it is much more easy going film.
If the movie is good, I would like to watch it again. What is the difference?
