There are no believable characters, no rising tension, and no scares in this Insidious meets Kramer vs. Kramer.

[A] dull and misogynistic affair that imagines multiple types of women as malevolent fiends who terrorize supposedly sympathetic men.

Despite an imaginative setup, Separation can't divorce itself from a lack of scares, tension, and underbaked storytelling that prevents emotional resonance.

The characters are flat, the themes shallow, and the emotional catharsis is stilted in every scene.
