Yeah, I don't see any appreciable difference in one statement or the other. "Provoking meaningful interpretation" and "evoking the inexpressible" are functionally equivalent. Meaning doesn't have to be intellectual, and interpretation doesn't have to be analytical. And for that matter, "popular entertainment has gotten better" is another idea that's so vague and all-encompassing as to be completely uncontroversial. It's possible there's an interesting take on it that I'm not familiar with, but it seems an awful like getting into "if a tree falls in the forest..." territory.
