I really enjoyed this puzzle. It wasn't easy for me, as you can see from my time, but solving the tough ones engendered a lot of "oooh, that's what they meant"s and felt like a triumph.
GODZILLA at 1A (Fictional character with a star on the Hollywood Walk of Fame) was a great start, followed, down below, by another fictional fabulosity QUEEQUEG (Friend of Ishmael). That section ended high on the hog with "What might come after a cow or a sheep? (EIEIO).
The entire bottom half of the puzzle went pretty smoothly. I even got ORDINAL for "Part of many a street name" even though you don't see that very often around these parts. The south east featured the excellent fill (and delicious) TZATZIKI (Sauce made with yogurt and cucumbers) and 46A: Weather phenomenon portrayed by Chris Farley on "S.N.L." (ELNINO) made me laugh just reading the clue.
The south west had some great stuff, too:
51A: Good to go? (TRAVELSIZE) - apt!
34A: One involved in mass production? (ALTARBOY) - ha!
33D: eBay feature (CAPITALB) - duped again, as is often the case with these kinds of clues, but this time, only until I looked at 61A: Storage units (BYTES)
39D: Cold evidence (SNEEZES) - no question!
So, as you see, it was all rainbows and unicorns until I got to the north east. That section had some real LULUS. Things went wrong from the top, as they often do. I patted myself on the back for remembering "essie," clued in Wednesday's puzzle as "Big name in nail polish," and confidently dropped it in for today's 9A (Nail care brand). UHOH. 100% wrong. I didn't know MOHAVE from the clue, I was working the "crazy" angle for 17A: Disturbed, maybe (no surprise there, I suppose), and "Strobe stuff" had me staring at the grid like a deer in the head lights. Not to mention ODOR for "Repute," CRATE for "Junk heap," and TRANKS for "Zookeepers' rounds, informally" - all tricky turns of phrases and OED definitions that kept me DAIKON. In sum, a puzzle full of PITH and vigor, like EVERYONE likes. :)
