Let Me Be Frank here, I did not enjoy SOTE very much due to its many issues, and, unfortunately, the final boss turned out to be their manifestation. I can understand why some people seem to like him, but I will never agree that this is Fromsoft's best boss design. This animation demonstrates my dissatisfactions with The Promised Consort.
