for LOTR to have Absolute Beauty, which by some odd coincidence, is a good match for what most of its readers think is beautiful.
Particularly when referring to the movie versions, you could consider this simply a storytelling device, similar to all the characters speaking English even in movies set in non-English speaking countries (or planets). It’s not that the Absolute Beauty of Middle-Earth is necessarily a good match for our beauty standards, it’s that it makes it easier for us to relate to the characters and experience what they’re feeling.
