Sometimes, a twist is the best part of a feature film. When the whole story leads to a big reveal that changes the way you see the movie, it's like a brand-new world of storytelling that just opened up. Sometimes, great twists can change a movie's genre, like in Parasite, which switches to a thriller halfway; other times, great twists make people want to rewatch the movie, knowing what they know now, such as in Fight Club or Shutter Island. Some movies are even improved by their plot twists, making them better in the long run.
