I think I love the way Brian Duffield’s brain works. Spontaneous is easily one of my favorite and most re-watched movies of the last few years; Love and Monsters, which he wrote but didn’t direct, is great; and now we can add his latest multi-hyphenated endeavor, No One Will Save You, to this pile as it does not disappoint. At a base level, this is an alien-home-invasion story, but the reality is so much stranger and more complicated than that.
