Writer/director Brian Duffield made an impressive helming debut with 2020’s “Spontaneous,” which explored human intimacy in the midst of exploding bodies, making for a highly unusual and absorbing viewing experience. He’s back on more familiar ground with “No One Will Save You,” which is an alien invasion story, going where many filmmakers have gone before as Earth is visited by strange beings most curious about the ways of human response. Facing formula, Duffield shifts course, crafting a bizarre survival story that employs almost no dialogue, hunting for a more primal feature that’s mostly built out of reactions from lead Kaitlyn Dever. “No One Will Save You” is slow-burn and protective of its mysteries, but the reward for such patience is a visually striking and periodically exciting chiller that heads in unusual directions, shaking off predictability early as the story finds ways to thrill and touch on the human condition.
