Sorted the list All the movies from @Hershey by the color of the film posters from light to dark.
If you have any ideas what else can be done with the posters (like the movie or anything else) just post it in the comments.
Unfortunately Letterboxd changes the posters every now and then. If you find a movie that doesn't fit, please post it in the comments ;-)
During the update letterboxd unfortunately went down. I hope everything worked out so far and there are not more glitches than before ;-)
Changed default sort from light to dark (maybe start with a color next update?)
For old sorting (dark->bright) just sort by "Reverse Order" (Browser) or "When added" (mobile)
