Studies show that drinking red wine improves cognitive function. I proved this theory recently when I spent a good portion of ‘Arrival’ shrouded in a mental fog, only to have everything click after a spirited discussion with my more enlightened (and obviously smarter) other half and a glass of wine … 57 minutes after leading the theater. By Jove, I got it. I understood Heptapod. I understood Hannah. I learned two things today: The movie is brilliant and next time, I’m sneaking not donuts, but wine, into the theater.
