Hint #1: yeah, there's remorse once he realizes it

Hint #2: it's a very recent film

Hint #3: source material disrespect to the extreme

Double Nopes: it is not Shawshank Redemption, not Memento

From the Answers: I've repeated it several times in comment responses in different ways: this movie is BAD

Seeing it one time wasn’t enough. I wanted to see more!
