Character development plays a role too. If a character has a hidden side that is revealed as a plot twist, it should be consistent with their previous actions and personality to some extent. For example, in 'Shutter Island', Teddy's true identity as a patient rather than an investigator is a major plot twist. But looking back, his strange experiences and mental states on the island can be seen as clues, and his character's journey makes the twist feel more earned.
Suspense is a key element. For example, in 'Gone Girl', the mystery around Amy's disappearance builds up the suspense, which makes the plot twist at the end (where it's revealed she faked it all) even more shocking. Another element is misdirection. The writer leads the reader or viewer to believe one thing, like in 'The Prestige' where you think the two magicians are competing in a normal rivalry, but there are much darker secrets.
One good plot twist could be that the character who seems to be the hero is actually the villain all along. For example, in a detective story, the detective who has been leading the investigation turns out to be the mastermind behind the crimes he's supposed to solve. It completely flips the reader's expectations.
A good plot usually has interesting characters, unexpected twists and turns, and a clear beginning, middle, and end.
One good plot twist could be that the person the main character thought was their soulmate turns out to be a long - lost relative. It completely changes the dynamic of the relationship and adds a whole new layer of complexity and drama. For example, they might have been on the verge of getting married when this revelation comes to light.
The discovery that the entire world the characters live in is a simulation. In a short science - fiction story, the characters are going about their normal lives until they start to notice glitches in the world around them. As they dig deeper, they find out that their whole existence is just part of a complex computer - generated simulation, which turns their understanding of reality upside down.
One good plot twist could be that the two characters who seem to be falling in love are actually long - lost siblings. It completely changes the dynamic of their relationship from romantic to a more complex family - oriented one.
A good plot usually has interesting characters, a clear goal or conflict for them to overcome, and unexpected twists and turns. It also needs a logical progression and a satisfying conclusion.
Good Christmas stories often have a strong sense of hope. For example, in 'A Christmas Carol', Scrooge's transformation gives hope that people can change for the better. Also, the presence of family and community is important. In many Christmas stories, families come together or a community unites during the holiday season. It could be seen in 'The Polar Express' where the children on the train are all sharing in the adventure towards the North Pole.
One element is the determination of the delivery person. For example, if they face bad weather or difficult terrains but still manage to deliver. Another is empathy. Like when they understand the urgency or special needs of the recipient.
One element is community spirit. For example, when neighbors come together to clean up a local park, that's a great hood story. Another is acts of kindness, like when someone anonymously pays for a struggling family's groceries. Also, unique local traditions can make good hood stories.
