That's right, DNF. I was stumped by 14A: Green card issuer, informally (AMEX), and I somehow convinced myself that "EnCITES" was equivalent to "inCITES," neither of which was as good as EXCITES (4D: Fires up). Sure, it's only one error, and I could have called "FWOE," but I could not figure it out before going to work, and I looked at the Crossword Fiend to see what the hell was wrong. It's a fine line, I guess, but I feel I can only call FWOE when I can quickly look at the grid and see what was wrong - and usually it's a typo. If I have to look it up, it's a DNF.
So now that we have that out of the way, I can say that it's another one of those "Wacky clues for normal things" kind of theme, and you might remember that it is a type of theme that I usually enjoy. Some of these, however, seem a little more tortured than usual. 17A: Eye an election official? (CHECKOUTCOUNTER) is a bit of a stretch. "Counter?" And 48A: Warning shouted to a lacrosse defenseman? (LOOKOUTPOINT). Yikes. TAKEOUTORDER and WORKOUTROUTINES are both solid, though. Also, all the theme answers hinge on the word "OUT," with the last answer having a bonus second occurrence of the letters. Overall, the theme gets a half-hearted thumbs up.
The fill, on the other hand, has a lot of meh. ONEA, ALII, DIY, TAS... and then there are the gratuitous plurals IOTAS, EWERS, MARKS, STYES. I don't put REARS (22A: They may be paddled) into that lot because of its fine, Huygensy clue.
The sevens are mostly good, though, with FLUNKED (43D: Didn't make the grade?), HOTPINK (47D: Popular color at Victoria's Secret), FINEART (10D: Pricey pieces), and - now that I know it - EXCITES being my favorite. The inner sevens are ok, but not great.
I don't really even mind FIEF (10A: Overlord's domain) and LIEF (42A: Happily, old-style), but I might not get too many supporters there. And isn't it odd how LIE sits just above LIEF? Is that a good thing or a bad thing?
Oh, I don't know... I didn't hate it, but I didn't love it. Let's call it a typical Wednesday wash.
