I loved this puzzle. I went through the whole thing again just now looking for rough spots, because after I finished I couldn't recall any. I found SAYA (44A: "Don't ____ thing"), and ILEA (5D: Guts, in part), which, after looking it up, seems a little too tricky. Our resident MD may want to weigh in, but when I hear "guts," I think of it as a collective noun specific to just one person. In each person, there is a part of the small intestine called the "Ileum." So to pluralize ileum to ILEA means that "guts" has to work as a plural collective noun, and I'm not sure that's quite normal.
But enough about that - accepting ILEA means that we get the lovely HEBRIDES (1A: Skye, the Small Isles, etc.) (a giveaway on a Saturday!), AQUILINE (15A: Eaglelike), JUKEBOX (17A: Brown-bag lunch item) (Not in my day!), and JACKASSTHEMOVIE (19A: 2002 "documentary" with "Don't try this at home" contents). That's a very nice NW corner! Being old and knowing RICKSPRINGFIELD (4D: Singer with a recurring role on "General Hospital") helped out in that region. Slowing me down, though, was my quick use of an alternate spelling of HAJJI (1D: Faithful pilgrim).
Everywhere you look there are strong mid-length entries and good clues. I'm sorry I started this review off looking for trouble spots, because really, it's pretty great. CUFF (41A: Strike sharply) is uncommonly good. CAREWORN (54A: Bowed with adversity), BADIDEA (35A: "No, you don't want to do that"), BITEME (40A: "Drop dead, loser"), SHODDY (57A: Third-rate), RODEO (25D: What may involve the calf muscles) (Ha!), MAXIM (28D: Saw), PILEUP (53A: Jam producer), TIPSY (43D: A little tight)... all good.
1A: HEBRIDES - A. Put "Decoy Bride" on your Netflix queue and watch it some night when you're in a good mood. It's silly, but adorable.
Favorite: END (33D: Patootie). So silly on a Saturday!
Least: MINICAR (38D: Subcompact). I've said it before and, knowing me, I'll say it again, I just don't buy this as either a generic term or the name of a specific car. Yuck.
OK, so it's not absolutely perfect, and I don't want to give Mr. Fromm a swelled EGO, but I say this one SHINED.
