SIFF Says: Finding that her new boarding school is overrun with ghosts, young Lilith calls on the Ghastly Brothers, a pair of professional paranormal detectives, to investigate. But they find these aren’t your normal, everyday spirits.

Stranger Says: Stranger Things meets Buffy the Vampire Slayer meets Ghostbusters in this delightful kid-friendly romp about ghost-hunters at a boarding school. Lively humor and puppets are a hoot (and often quite gross), and ghosts are a neat metaphor for wrestling with emotional demons of impending adolescence. Copious Dutch puns are valiantly localized with varying levels of success. (Haunted bird: “Poultrygeist.” Haunted refrigerator: “Frightdge.”) Young viewers may balk at having to read subtitles, and parents at the occasional profanity. MATT BAUME
