I'm with you, tatters. I avoided this week's theme for a similar length of time, mainly because everyone seemed to be going crazy about it!
The 'epithet' seemed to me to be a random collection of letters - even after I had spotted that I had done my usual trick of finding the correct letter for the misprint in one clue, only to write a different letter! After staring at it for a long time, I resorted to simply giving the whole string of letters to Google Assistant and the nice lady sorted it out for me.
I finally managed to complete the grid by filling in the unchecked letter in 37d at 22:56, so that's a PB for me!
(I still can't parse 8d though, but, like so may other lights in this puzzle, it has no unchecked letters, so no nudges or hints required, thanks; it will probably come to me as soon as I hit the 'Add Post' button.)
