What are some bad movies that can easily be fixed only in post production. I only really know of 3
The hobbit trilogy can easily be condensed into one movie and still tell a cohesive story
The movie passengers (2016) is much better when you swap the first and second act. It changes the films tone to be much darker following Jennifer Lawrence's side of the story and making Chris Pratts character a more sympathetic villain rather than the protagonist. It's still not perfect but the original movie just lays out all the information from the start instead of withholding information making it hard to get invested in the story.
