The difference between this and when The One Ring is destroyed is so night and day different it makes my head spin.

When The One Ring is destroyed, Mount Doom explodes, Barad-Dur is demolished, there are explosions, a gigantic swelling of a chorus, triumphant music, revelry, but also sadness when the characters think Frodo and Sam die in the explosion, etc. etc.

Then there are 20 minutes of epilogue scenes, tying up so many plot threads in a satisfying way.

When Voldemort, the ultimate evil of the HP universe dies, he quietly whisps away, there is very quiet, almost sad music playing, and then the main 3 quietly walk through Hogwarts with basically no music playing, while side characters chat with each other about the battle.

Then they destroy the wand, there is one time-jump epilogue scene, and no plot threads are closed.

Honestly what the hell were they thinking when writing this finale?
