CinemaScore polls only occasionally produce low grades, which is why it’s eyebrow-raising when something scores as low as a D+. Lately, almost everything that has been polled has gotten a B or higher. Spider-Man: Into the Spider-Verse is the most recent film to earn an A+ score, which is also rare. Creed II, Instant Family, The Upside, and On the Basis of Sex all got an A. Aquaman, Bumblebee, Mary Poppins Returns, The Grinch, The Mule, Ralph Breaks the Internet, and A Dog’s Way Home all got an A-. The most recent scores below a B include a C+ for Vice and a C for Replicas.
