‘Onslaught’ Review: Adam Wingard Goes Back to Basics with a Lean Military Slasher

Adam Wingard's low-budget action-horror film, "Onslaught," promises fiery action but fails to deliver. The movie, starring Adria Arjona as ex-Army sniper Celeste, wastes time with character development and a vague theme of war's contradictions. Despite featuring notable actors like Reginald VelJohnson and Eric Wareheim, the film's uninteresting plot and disappointing action sequences make it a letdown for fans of Wingard’s earlier works like "You're Next" and "The Guest."

While Arjona shows promise as an action star, Dan Stevens' performance is underutilized. The cinematography is praised for its style and confidence though the climax feels abruptly cut off. "Onslaught" opens in theaters on September 4, but ultimately falls short of its explosive potential leaving the audience unfulfilled.
