I caught on to the theme, whatever it is, within the first couple minutes, and all but the NW and SE were done in about half of my final time. 13A: Goldfinger's first name (CIRUA) ("Auric") was particularly tricky, and I wasn't really expecting the backward thing up there, because, well... let's see, ... ok... I figured it out!
So, overall, I love this puzzle. I love this kind of a "free-for-all" theme, where the constructor is allowed to bend the rules of puzzledom. It's something like what you see in "Puzzle Five" at the A.C.P.T. every year, and it's something that hardcore puzzlers (or at least this hardcore puzzler) very much enjoys from time to time. And for this amount of work, I am willing to accept NORTHER, ASOLOPE (50D: Slanting), STEGOSAUR (without the "US" that I'm so accustomed to), and pretty much everything else that's questionable.
My favorite entry might be CIMONOGRE (22A: Like some office furniture) ("ergonomic"), because it looks so cool. Like a French word. ("Il est un brute! Un vrai cimonogre!...") And speaking of French, Frannie and I just walked past the "Temple of St. Eloi" in Rouen tonight. (It's today's photo.) I suppose it's a little outré, comme idée, but maybe that could become an alternative cluing for ELOI (31A: Morlock victims, in science fiction). ... yeah... probably not. And also speaking of French, NANAS is slang for "hot babes" in French, but I like today's clue even better - "Spoilers?" As in, those who spoil (their grandchildren).
OK, that's probably enough French for now. There's always demain. But before I sign off - 1A: 50s president (GRANT) gets a B. I appreciate the attempt at misdirection, because we all think of Truman and Eisenhower. Once I realized they wouldn't fit, I went to the 1800s and thought of "Tyler," because who knows, really. And he was close ('40s). But Grant wasn't president until after the war. He didn't start until '69, so the clue would be almost two decades off! ... But! He is on the fifty dollar bill, so I guess it's legit. Damn! That's a tough one!
Still, as I said, I love this type of thing. I'm giving it a big thumbs up.
