Today we have four place names that contain two instances of "la," or, four examples of LALA LAND. It's a cute, simple, Monday theme, and one of my brothers is living on the MALAYPENINSULA these days, so it was fun to see that in the puzzle.
1A: Pitchfork-shaped letter (PSI) - B+. Nice clue for this one. I tried "wye" here first. Is that how one spells the second-to-last letter in our alphabet?
Favorite: 15A: Animal whose name is a synonym of "parrot" (APE). Heh.
Least: AFROED (17D: Sporting a natural) - Has this ever been said? "Oh yes, he's the afroed gentleman..."
Not much stellar material, but very little that's terrible, and we've got plenty that's pretty good, to wit: POMADE (14A: Hairstyling substance) (Makes me think of "O Brother, Where Art Thou?"), FLUKE (50A: Happy accident), FERAL (50D: Wild), and IGLOO (3D: Ice pad?) were all interesting. I could do without OOPSIE (5D: Mistake, cutely), and it was a little too bad that PERFECTGPA wasn't something theme-related, but overall, I enjoyed it.
Horizontal symmetry, theme answers running in both directions, which I tend to like, plus, an interesting theme and a fun revealer, all add up to a fun Monday.
