The theme deserves, I suppose, a measure of respect, for pointing out such a metrical miracle as EMILYDICKINSON's DOUBLEDACTYL, but I sure had trouble with what was effectively 43A, the last part of the question. It may surprise you to learn that even though I entered the poet's name quite early on, I didn't immediately consider her feet, or is that foots? So, I in turn, have a question for you,
What famous crossword puzzle blogger, who took forever to think of dactyl, could be aptly described with the spondee dumb dumb? Answer below. :)
It may be that because I was unable to tear a dactyl out of my brain, my feelings towards the puzzle as a whole suffered a bit. It's a solid puzzle with some clue-to-answer exactnesses that I always appreciate such as 34A. Handle adversity (COPE), 35A. Feel some repentance for (RUE), and 42A. Checkup imperative (SAYAH), but that it might have lacked a little VOLTA.
