Paste Magazine offers the 10 most rewatchable movies.
For those too harried to click a link, they are:
9. Napoleon Dynamite
8. Pulp Fiction
7. Spaceballs/Robin Hood Men In Tights
5. The Princess Bride
4. The Ten Commandments
2. Groundhog Day
1. The Shawshank Redemption
Their honorable mention list: Casino, Forrest Gump, Fast Times At Ridgemont High, Amelie, The Sound of Music, Inherit The Wind, What About Bob?, Snatch, Lawrence of Arabia, Hoosiers, E.T.: Extra Terrestrial, Zoolander, To Kill a Mockingbird, Pretty Woman, When Harry Met Sally, The Sound of Music, Corky Romano
I get how most of the first ten made it onto the list, with the exception of The Ten Commandments. It's one of those overdone Biblical spectacles, and Heston overacts, as usual, in the Shatner League. But Corky Romano in the honorable mentions? Somebody's smoking something. And there is ot ONE mention of a Python film. Each one of them is rewatchable as hell.
