Movies like Bad Sister

“Bad Sister (2015) is a 2010s Canadian-American psychological-thriller that frames institutional betrayal through intimate domestic lenses. It stages a teenager's suspicion of an infiltrating authority figure against high-contrast chiaroscuro, tight frame composition, and economical practical lighting. The film insists that contained religious spaces can intensify private boundary violations, producing a cinematic aftereffect of lingering mistrust that rewards sociological reading.”
