[RockyIII]

There seem to be good, bad, and ugly UHDs on the market right now. But in your opinion, what are those UHD titles that offer the greatest rewatchability factor? There are movies that, as great as they are in UHD, you just cant see yourself ever watching again in your lifetime, but there are others that you know you can't wait to watch again as soon as the end credits roll.
Name a few UHDs that due to HDR, sharpness, plot, cast or a bit of all of the above, you consider titles that you will be watching over and over again and still discover new nuances and details you missed the previous times.
