"A tricky film to advertise without revealing its conceit — even its distributors have largely avoided disclosing the nature of Justin Long's role — Barbarian plays like a midnight festival darling, bucking expectations while maintaining artistic finesse... The film's rapid swinging between styles can be distancing at times, with shifts in narrative focus that often arrive just when the tension begins to crescendo. But these mildly jarring resets are part and parcel of the film's devious game of tonal hopscotch, and Cregger knows exactly how and when to twist each screw, reminding the viewer how funny, intense and disturbing a movie can be, all at the same time." - Siddhant Adlakha, Empire Magazine
