>>64077457Conclusion has always been the hardest part to nail in media. Knowing how to close out a story in a satisfactory manner that leaves the readers/watchers/players happy is tough for a lot of reasons.
1. You simply can't please everyone, and some fans will not like how things turn out no matter what you do
2. All the stuff you wrote in? Well you better have had plans to tie it all up it address it in some way, otherwise there will be criticisms regardless of how good things are overall
Example, Eagles Ring Drop discussion in regards to LotR, Mass Effect 3 leaving players dissatisfied that their choices didn't matter outside a simble RGB choose your color3. A Conclusion should leave the readers/watchers/players thinking after its over. Be it just thinking about how happy they are with how things turned out and about how the characters are entering a new age/life of peace/hapinness/fulfilment, or wondering what the ending means for the cast, or about their own lives/the world/the universe.
3A. Happily ever afters can be done well, like LotR, and Witcher
3 Family Ending+:Blood & Wine/Original ending for the books, but part of that is establishing that you can see a good forward trajectory for all the troubles the characters went through. If you took Star Wars the original film as its own piece of media that never got sequels, it closes out very satisfactorily for example.
3B. The next side is uncertainty/consequence, and how the film provokes a desire to find out what happens because of how things turned out. It stirs your imagination on how what went on in the media will affect the characters for time to come, usually in either a negative way or a way that makes things uncertain. This is also usually the best way to set up for sequels, just think of the John Wick Films for example, or any media that ends on a cliffhanger that makes you want more.
3C. The last is things that provoke your thoughts after the conclusion. This is usually more of a personal thing but maybe a media made you feel a revelation by it's ending, or gives you wisdom you apply to the real work or simply makes you question certain things and ponder on them. Good example for this is SOMA, IMO, which made me feel real existential dread due to it's ending.
A good ending can leave audiences happy without having to go further or spur intense desire to see more media produced in that universe.
The TL;DR being: writing a good ending is TOUGH work to leave audiences satisfied.
