OYS! A scary puzzle for Halloween. TID, SWE, TOA, OHO, CMD, REN, HIN, THD, RMS, LIQ, LEV, TVPG ... it RANKLEs. Even the stuff that I might ordinarily like, like 100D: Like some Roman aphorisms (SENECAN) (Like how I got three likes in a row there?) is ruined by the adjectivizing.
The theme is a sort of "before & after" combining (supposed) Halloween costumes with people's names. As in EYEOFNEWTGINGRICH (58A: Halloween costume for ... a onetime House speaker?). I'm not sure which end of that one is more scary... and how many kids are going out as an "eye of newt" this year? TOMBSTONEPHILLIPS (39A: Halloween costume for ... a former "Dateline" host?) is another popular costume, right? A tombstone? Blah.
I just didn't like much of this. COZENER (12D: Con man), SCAPES (45D: Vistas), TRALA (120A: Insouciant syllables), SEEPY (33D: Like ooze), GUCK (87D: Slimy stuff)...
A DUD, in my opinion.
