Similar to Saulnier’s Green Room and Blue Ruin , the violence is fast, swift, and unforgiving, though unlike those two films, it’s never connected with dread.
Although there is nothing remotely original or nuanced about Becky – a formulaic thriller that hybridizes Straw Dogs, Home Alone, and Green Room – there’s an undeniable grindhouse pleasure in watching a 13-year-old girl murder the hell out of some Nazis.
This kind of casting against type can be effective; think of Patrick Stewart, subverting his regal dignity to play a Nazi kingpin in Green Room (a film roughly 20 times as intense and visceral as this one), or of Albert Brooks proving his range as the decidedly non-humorous, razor-wielding crime boss of Drive .
As a merciless depiction of a fascist monster by an affable figure, it's right up there with Patrick Stewart and his gang of Oregon fuckheads in Green Room in the unexpected stakes.
