The result is dizzying, disorienting and sometimes draining.

As fun as it is to see Hannah fronting the action, though, this puerile exercise in hyperactivity and eye-gouging hyper-violence gets pretty tiresome pretty quickly.

Though its point comes a little too late to land cleanly, it’s effective at emphasising the absurdity of the frantic carnage that came before it, concluding with an original, quietly devastating idea that lands with a real punch.

Its turn-of-the-millennium videogame quality extends to the film’s dramatic chops. While Hannah’s cheeky charm occasionally manages to shine through, Karl is exactly the sort of blank slate protagonist that once dominated gaming.
