100 Nights of Hero wants to be a swoony, modern fable and ends up a tidy, sanitized fantasy. Maika Monroe remains close to appointment viewing for me, especially in bleaker work like It Follows, Watcher, and Longlegs, where her soft spoken cool lets dread lurk. Here the role asks for more spark than the movie can draw out, and the energy deficit spreads to everything around her.
Cherry, played by Monroe, lives with her husband Jerome, played by Amir El-Masry, in a sprawling country house. Convinced she will stray, he exits for one hundred days and invites his seductive friend Manfred, played by Nicholas Galitzine, to test her fidelity. Emma Corrin appears as Hero, the maid who narrates and shades the tale. The pieces are in place for a thorny adult romance with bite.
Instead the film keeps things oddly chaste and frictionless. The fantasy romance pastiche plays like Saltburn stripped of its edge, with courtship games that refuse to court danger. The feminist framing is not wrong in principle, it is simply obvious and repeated until it becomes the text. Once the light sweetness wears off, there is not much underneath.
The performances flatten under the house style. Monroe leans into her cool reserve and never quite locates Cherry’s wants. Corrin holds back in a similar register, which turns Hero into a tidy device rather than a destabilizing force. Galitzine and El-Masry do what they can with roles engineered to represent rather than complicate. Cameos from Charli XCX, Richard E. Grant, and Felicity Jones should add fizz; the dream sequences in particular stall out before they can leave a mark.
The quasi modern classical aesthetic does not help. Rooms are immaculate, costumes crisp, images polished to a gloss that repels mess. The film gestures toward sensuality and danger, then keeps cutting away from both. You can see the movie it wants to be, a bedtime story for grown ups with teeth, and you can feel it choosing safety at each turn.

There are scattered pleasures, mostly in the way the camera frames corridors and courtyards like illustration plates. They register as style rather than feeling. By the final stretch the plot is pushing characters around to make a point, and the point was clear an hour earlier.
100 Nights of Hero is not a disaster, it is simply thin. The ideas are heavy handed, the romance is tame, and the cast is stuck playing types.
Score: 4/10
