Siegel™’s review published on Letterboxd:
Primarily a thriller, as all good genre movies are; at their core, horror, action, even comedy rely on the building of tension, and it's how it is handled that classifies each as a member of their respective genres. Carnahan proves to be surprisingly patient, especially in such a fast-paced adrenaline rush of a film, comfortably building suspense and then wallowing in it for unnerving stretches of time. It's an action movie through and through, but its formal elements are reminiscent of slasher flicks, with echoes of Tarantino, noir B-movies of the 1950s, and even westerns. About 20 minutes into the film a thought crossed my mind: "Damn, I kinda hope this never ends." Although ultimately, I kinda wish it actually did end, because closure is the only missing element to this epic guilty pleasure explosive extravaganza.
