Since I live in a forced hot air house, I dropped in DUCTS (1A: Heating system network) without a second thought. I then thought I might have a chance at beating yesterday's time when I confidently plunked down CobwEbS for 3D: Haunted house sights (CASKETS). Obviously, things slowed down a bit after that.
There were a few fun answers, like LOZENGES (10D: Hackers' helpers) and DISCOBALL (30D: One lighting up the dance floor), but all too often it was questionable stuff like TWEEST (4D: Most affectedly dainty, to a Brit) and DEADEST (40D: Least happening), or stuff I didn't understand like SENS (5D: Political century: Abbr.) and AVES (20A: Class of fliers?). Also, while I'm glad that the puzzles are getting more contemporary, I lament that it proves me to be no longer so. I have never heard of ASAPROCKY, and the expressions CANILIVE and NOBIG are not in my vocabulary.
I don't mind things I am not familiar with (to which category may be added HOURANGLE and DAYSAILS), but I didn't feel that there was enough to really enjoy today either. Entries like ENCIRCLES, ICEIN, STIRSIN, OWIE and EENY are not exactly exciting. Even VENALLY (12D: Through bribery) is tarnished by the adverbialization. Is that a word? Does its existence here tarnish this review? Possibly...
1A: DUCTS - C+.
Favorite: 26A: Setting after resetting (OOO). I like the boldness of this one.
Least: I guess TWEEST. Just ick.
So, as you can see, I didn't love it, but I think I may sound a little more harsh than I actually mean to be. I didn't hate it either. Can we settle on lukewarm?
