Lightweight caper, hugely foreshadowing the plot Hanna-Barbera rehashed so many times for Scooby Doo. Three kids hide out in a haunted castle, trying to help the titular ghost reconnect with its head, but having to deal with obstacles along the way. If this was a sharp cracking, effects-driven family frenzy, it’d struggle. Given the film’s vintage, the love interest and castle’s apparent hard times being suffered, there are some diversions away from the central caper. The main characters suffer from being cartoon thin. At best, the fail to engage; most of the time they’re irritating. Confused, shambolic and irritating. Still, the poster’s good.
