Here's a puzzle where I knew most of the answers immediately, but didn't get anywhere near the four minute mark. Maybe some day.
I'm going to shoot for PITHY today as I have a date with Mr. Overholt in less than an hour. I hope I won't reach the POINTOFNORETURN with him. Which brings us to today's theme. I liked BERMUDATRIANGLE. It runs the full length of the grid, and, I was fascinated by it in my youth. I think we even had a game called The Bermuda Triangle. The other theme answers are solid 'Points of no return', with TENNISACE providing a nice twist on the word point.
The puzzle kicks off with an abbreviation ATTY, and a rather unappealing one at that, but most of the rest of the threes aren't too bad. My favorite is the enjoyably rephrased old standby: Tango requirement (TWO). I liked the combination of passion and brains to produce NERDY. Also, 4D. got a YUK, even though it's only the start of a joke (YOMAMA).
I was less happy with the clue for 35A. Jazzy Fitzgerald (ELLA). It seemed too glib a description for her talent. And, I realize Monday puzzles are supposed to be relatively easier than puzzles later in the week, but when I got to 34A. WSW's opposite, I wondered why they didn't simply write, "34A. Enter ENE." Perhaps that would leand to ENNUI.
