Time Cut is a frustrating film, twice over. On the one hand, it takes a genre conceit that should be a layup and sleepwalks right through it, in a way that implies the audience deserves no effort beyond what it took to get them to press play. As if those who love slashers or time-travel movies are won over by premises alone, not the passion and creativity of their execution. Certain scenes left me feeling more insulted than disappointed.
