aka The Orphan
How bad is it? It's slow and uneventful, but not terrible.
Should you see it? Yes, because it's interesting.
Filmed before the slasher series it shares a title with, this gets poor reviews by those hoping for a gorefest (there's two murders, neither gory). It was filmed over a decade, 30 minutes got cut and only a poor quality print is available. It's a strange, dream-like, arty psychological horror, where the tone shifts too often, the plot veers wildly and the acting is not expert. An explorer's son is orphaned in an accident and his aunt tries to re-mold the boy, chasing away his only friend and killing his pets. He hears the maid having sex, goes crazy and starts a rampage of revenge on the aunt.
