Setting aside unique exceptions like the Get Out meta-ending, how would the viewer interpret it if you made the MC judgment the opposite of the storyform--and it was done skillfully? For example, the storyform says judgment bad, but the actual ending has a judgment good. Assuming it was done well, could it feel like an unexpectedly positive ending? Or, even if done well, would it necessarily feel tacked on and inconsistent?
I feel like this is impossible to think through with counterfactual examples to existing movies like "what if Hamlet was finally content at the end?" or "what if Clarice's lambs stopped screaming?" because I've already anchored the first impression of those movies and they are what they are.
