In The Shawshank Redemption, it’s revealed Andy did not kill his wife. But how is he supposed to be redeemed if he was never bad? What a stupid title.

In Arrival (2016), the Heptapods taught Amy Adams how to alter time. Later in the movie, it is revealed that they’ve actually taught it to her before, but she used it to reset her life due to the loss of her family, then the aliens had to teach her the same shit all over again. Dumb bitch.
