10 Time Travel Movie Rules, Ranked Worst To Best

Sometimes a movie can sacrifice its time travel laws for the sake of drama, and it ruins the whole premise of the story, effectively disappointing viewers. The Butterfly Effect violated its time travel rules with a single frustrating scene where Evan traveled back in time to convince his inmate of his abilities, which defied all in-universe logic.
