I love a well-acted film--especially a classic Ghost Story. The two schoolgirls, one of whom is being haunted in her family home, are perfectly on cue with every word spoken, with body language, with facial expression. Quite a good film with some genuinely scary moments. Characters are well developed. The story is allegedly based on true events, similar to the Enfield Haunting films Conjuring II and the somewhat-plodding BBC miniseries starring Timothy Spall.
