Charlie and Sally and summer camp, oh my! The “Peanuts” creator Charles Schulz believed there wasn’t enough innocence in the world. His beloved characters provided some. Apple TV+’s Snoopy Presents: A Summer Musical, the first Peanuts musical in over 30 years, celebrates the magic of summer camp, friendship, and family. The plot? It’s Sally Brown’s first summer at her brother Charlie Brown’s beloved camp—just as he learns it’s about to be shut down. Determined to save it, Charlie and the “Peanuts” gang team up to keep the camp alive for summers to come. With nostalgic characters and fresh songs such as “Look Up, Charlie Brown,” “Best Time Ever,” and “Leave it Better,” this musical illustrates why “Peanuts” has been a classic for 75 years. —Alexandra Lemer
