Patrick Berry is fast becoming one of our favorite constructors. His grids are almost always clean, meaty without being overly so, chock-full of fun stuff, and what's more … we seem to be right on his wavelength. This one starts out strong with two tricky clues 1A: Attaché feature (ACCENT) (why did this take us so long?!) and 1D: Bread boxes (ATMS) (Frannie nailed this one immediately). We ended not far from there at the intersection of another tricky pair, 23D: Flimsy lock (WISP) (we could only think of the locking kind of lock) and 23A: Not down with anything (WELL) (beautiful).
In the middle, we credit a year of NYT Crossword solving for our laying down OATERS (28A: Many old B films), and off of that (and maybe one other) we got COPACABANA (24D: 1978 disco hit featuring the warning "Don't fall in love"), which really opened up that lower middle section.
So many good clue/answer pairs today. PREACHERS (37A: They deliver on Sunday), PIGEONS (51A: Common gathering in a public square), OCTAVE (50A: La to la, e.g.), CHEATSHEETS (16D: Cribs), THENCEFORTH (14D: Ever since that time), and more! I also have a fondness for the very straightforward answer that is hard to see at first, a good example of which today, at least for us, was ELDERLY (4D: Aged).
A very enjoyable Friday.
