"Claudia and the Phantom Phone Calls" is a terrific introduction to Claudia's love of art and her issues with school. However, it doesn't give the phantom phone calls or the Halloween setting the spotlight it deserves. It's totally understandable for the writers to focus on character growth over holiday fun in season one, but the BSC has a long history of getting entangled in spooky mysteries. The world needs to see The Ghost at Dawn's House or Stacey and the Mystery of Stoneybrook adapted for the small screen — with some modern flourishes, of course.
Maybe Netflix should consider an expanded episode order for season two to make room for a standalone Halloween episode to give the sitters a chance to properly get their Nancy Drew on.
