“Whalefall,” a survival thriller starring Austin Abrams and Josh Brolin, premieres in theaters with outlets reporting generally positive early critical response alongside notable reservations. Multiple reviews describe the premise: the protagonist survives a scuba-diving disaster and is trapped inside a whale’s digestive tract, leading to a race against time to escape.

Review coverage varies on tone, effectiveness, and whether the film leans into horror or more earnest emotional drama. Some sources praise elements such as the film’s gripping pacing, earnestness, and underwater body-horror effects, and highlight performances by Abrams (and Brolin) and the film’s attempt to adapt Daniel Kraus’ novel faithfully. Others characterize the movie as preposterous or take issue with how serious it takes itself, with criticism also aimed at the visual effects and the overall level of fear compared with its grossness and claustrophobia.

In reporting around a Los Angeles debut, director Brian Duffield and star Austin Abrams frame the film as distinct from classic “Jaws”-style shark stories, while review aggregations and individual critics note that audience and critic reactions are not fully aligned.
