A little over 12 minutes
I finished this puzzle on the way down to Rehoboth Beach in Delaware, and since I left the iPad in the car, I don't have access to it to find out the exact time of my finish.
I found this puzzle satisfying, and if it suffers somewhat in comparison to yesterday's tour de force, it's still an very fine themeless puzzle. It is a truth universally acknowledged among the creators of this blog that the Thursday-Saturday set of puzzles are the ones with the most enjoyability; sadly, my recent experience with the Thursday puzzles haven't been at the same level, so I rely heavily on these two themelesses.
I broke in to the grid in the NE corner for once, with the gimme Michael SCOTT. Even after finishing the area, I had no idea why DEVILDOG meant "Marine." Turns out it's a standard nickname for the branch of the armed forces.
The best of the puzzle comes across the middle: SAMESEXMARRIAGE of course is a lovely 15-letter answer. But I enjoyed the clue of 21D: Film featuring an assassin from 2029 (THETERMINATOR). It's amusing to realize how far in the future somebody thought that year would be.
Other good answers include 32D: Vessel in a famous 1960s shipwreck (SSMINNOW) - I love the unexpected fictionality of the Gilligan's Island ship. The symmetric answer in the other corner also has an atypical double letter in AAONLINE.
A puzzle that references Pogo (OPOSSUMS) is welcome. One of my all time favorite comics, and the source of the line "We have met the enemy, and he is us!"
Finally, I keep on wanting to misparse NOIRON as "noir on." Which I will now use whenever we decide to watch a hardboiled detective series.
