The movie “The Royal Tenenbaums” is adored by those beset with existential angst. Read: most of you. If you don’t cling to the absurd humor of it all (“it” being life and/or this movie), you’ll be thrown overboard and drown in the overwhelming sadness. See the cult classic for free Thursday in the Wexner Center Plaza. It’s the first installment of the arts center’s popular annual outdoor summer movie series called Wex Drive-In. There will also be a cash bar, food and — don’t disappoint me, people — many Margot, Chas and Richie Tenenbaums on hand.
