Digimon/Tear Jerker

The Franchise as a whole

 * Any Digimon finale is a Tear Jerker. It's always heartwrenching, even on the fourth watch to see the chosen children be separated from the Digimon they spent 50-odd episodes bonding with and saving two worlds with. 02 doesn't have the separation, but by the time you see the Distant Finale you're still in tears over Oikawa (and, quite honestly, you might be crying for completely different reasons).
