What are some bad adaptations?

Some notable bad adaptations include "The Last Airbender," which was criticized for its poor characterization and deviation from the source material of the beloved animated series. "Eragon" also fell flat, failing to capture the magic of Christopher Paolini's novel and suffering from weak performances and a lackluster screenplay. Another example is "Catwoman," which strayed far from the original comic book character, resulting in a film that was poorly received both critically and commercially.
