I rarely post in this forum. But I recently spent several hours, as a result of a minor COVID exile, re-watching all three. On these forums, when the movies came out there was discussion after discussion about what members liked and did not like, what actors we liked and did not like, and changes or omissions from the books.

While watching the movies again, a slightly different question occurred to me. Tolkien, perhaps reluctantly, sold the movies rights to LoTR and the Hobbit during his lifetime. However, he avoided conveying to rights to companies that he believed would eviscerate his vision of Middle Earth. So my question is, what specifically would JRRT have liked or particularly disliked about the movies?

This question is limited to the LoTR movies. I suspect that tomes could be written about the Hobbit movies and RoP.
