(spoilers)
It never sat right with me that Andy is shown to be innocent, and some viciously evil irrelevant character did it instead. This, I thought, takes away the whole redemption aspect of the movie, turning Andy into an innocent Mary Sue. I'd never considered that it may be more about Red's character instead. Though I didn't catch a satisfying explanation for that idea in the review, and it's been a long time since I watched the move.
I think I'll rewatch it today.
