Quite a clever and fun theme today! It took me a minute or two (see above) to catch on, but once I did, I had a great time with it. It's "just what a theme ought to be," said she, "sensible, good-humored, lively" - if I may borrow from Jane Austen for a moment. The theme pattern is strong, but not so strong that once you figure one out, you've figured them all out. The answers are common, natural expressions, and some of them made me LOL. I think 31D is my favorite: Where "menial" is in the dictionary? BENEATHME. Ha! BYITSELF is another good one (Where "isolated" is in the dictionary?). I could go on, but you've all done the puzzle yourselves, or you wouldn't be here.
Other bright spots include 26D. Glam rock? That one was a GEM. :) The clue at 61A (A small amount in science or a large amount in business) decidedly uptarded an old groaner like MIL. I was also très contente that 55D. (Parisian possessive) was MES and not ATOI, for once. Merci Mr. Mahnken!
I am giving 1A. "Exodus" hero (ARI) a C. It's not horrible, but it does nothing to draw one in, nor does it offer a hint at the fun of the rest of the puzzle.
My least favorite clue today is 35D. "After this, it's my turn" (IGOTNEXT). Both clue and answer are contrived and artificial 'sayings'. If I was playing a game with a person who actually said to me, "I got next" I would stare at them - taking another page out of Ms. Austen's book.
