What’s a movie that has you rooting for someone from start to finish, only to have the story completely flip your perspective by the very end? Which films have pulled off twists like this best?

I just finished watching The Guilty (2021) film that truly kept me on the edge of my seat from start to finish. IMO, it was intense, suspenseful, and thought-provoking. The way the movie manipulated perspectives was brilliant; it's a gripping thriller that masterfully plays with viewer expectations. Are there any other films that have pulled off similar twists and kept you just as captivated?

Edit: I just found out that so long movie name is censored with a bar, it should be okay to share.
