I’m gathering my own thoughts on the recently published Fall of Arthur poem by Tolkien; in the meantime, here are a few reviews.
John Garth, “Tolkien’s Unfinished Epic: ‘The Fall of Arthur.’” The Daily Beast.
Elizabeth Hand. “J.R.R. Tolkien’s ‘Fall of Arthur’ and the Path to Middle-Earth.” Los Angeles Times.
Some brief comments also appear on a couple of blogs:
Bruce Charlton. A brief review.
