No truly interesting movie can be subject to a single interpretation—even if the writer and director say it’s about one thing, some viewers may have a different take. That said, here are the movies that most would agree have been misunderstood throughout the years.
I would add “Crouching Tiger Hidden Dragon” to this. Everyone I know recalls that movie as: “They could all fly, and in the end, she flew away off the bridge to live happily ever after”.
I interpreted the movie as a total tragedy of the main character’s life, and, in the end, she jumps from the bridge to commit suicide.
Maybe I’m wrong though.
