A joke belabored is a joke ruined. “Superintelligence,” Melissa McCarthy’s latest team-up with comedian, writer, director, and hubby Ben Falcone, ruins an overwhelming majority of its jokes. Why does McCarthy slapstick need explanation? In an early scene with Jessica St. Clair and Karan Soni, playing tech world hippie dips whose casual free-spirited babble disguises their stealth mean girl sniping, McCarthy hops on a chill sack and immediately slides off like butter melting off of stacked pancakes; the bean bag chair is just too tall. Helpfully, St. Clair and Soni point out that the bean bag chair is just too tall. McCarthy tries again. She slips again. Once more it’s emphasized that the bean bag chair is, in fact, too tall, in case we haven’t gotten it yet.
