I think it's due to a general decline into literalness.
I'm not sure which came first: audiences that no longer understand symbolism, metaphor, allegory, or writers who no longer use it. In any case, all of these things are basically completely absent from any modern piece of mainstream media. Wherever there's an attempt, it's decidedly conspicuous. There's little nuance and subtlety.
