Kristy, Claudia, Mary-Anne and Stacey are back. Netflix has adapted the book series The Baby-Sitters Club, and hopes to reintroduce it to young viewers, nostalgic millennials, and anyone else who longs for days spent with friends when worries aren't too worrisome. Starring a cast of fresh young actors, and a few familiar faces among the adults, the show is getting solid reviews and might be just the thing for summer viewing.
