I'm pondering: How sure are we that Joe doesn't literally have dementia to the point (or is an actor playing Joe) that he A. doesn't remember/realize the shit he's "done" is so fucked?
I'll say one thing and say it only once.
Don't expect this movie to end how you anticipate. But expect that it'll end how it's supposed to and that we should all be better for it. Those that want to see, at least. Not just see. You have to feel. To truly feel we do have to sweep up the bullshit to protect the innocent and weak (no, you don't throw your weak to the wolves. That's fucked). There will always be someone who cares.
