If you loved Sisters, try Raising Cain
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Brian De Palma, and they both carry the mindfuck, paranoid mood tags, and they sit in Horror / Mystery / Thriller territory. If that's the register that drew you to Sisters, the second film will land in a comparable space — through a different lens.

What Raising Cain is
Upstate New York. Autumn leaves. A child's singsong counting. Carter Nix, devoted spouse and father, is also Cain, his malevolent twin, manipulated by a mad-scientist father. Wifely infidelity triggers a murderous spiral. De Palma's psycho-sexual thriller is best approached as high camp.
