No One Will Save You is an interesting alien invasion flick. The biggest element that sets it apart is that there is no dialog. It’s a heck of a goal that is hard to pull off, to say the least. Writer and director Brian Duffield largely pulls it off because lead actor Kaitlyn Dever who plays Brynn is so good.

Brynn is a young woman who lives alone in a rather rural area. The main town she lives near appears to be small, with one main street where all of the businesses are located. Her house is all alone in the woods. Going by the few shots of her road, you can’t see another mailbox or driveway. So when things pop off, she’s not running to the neighbors for help…not that they would welcome her with open arms.

At the start of the movie, it’s made clear that something happened in Brynn’s past that’s made her a loner. When she goes into town to do some errands, she’s anxious about being in public. All the side glances and murmurs aimed her way make for a rather uncomfortable experience. It’s hard to tell what this could be about. She looks like the girl next door who wouldn’t say or do anything bad to anybody. The way the scene is presented made me wonder if her anxiety was making her overreact. Maybe she was being paranoid, thus noticing unrelated things and attributing it to everyone being wary of her.

There is a lot of great foreshadowing done at the very beginning that quickly comes into focus before the second act starts. The aforementioned anxiety and then there’s the odd circular mark burned into her front lawn. It looks like it’s from the sun or animal urine. She puts some water on it when she notices and goes about her day. When she returns to the safety of her home, she gets a visitor at night.

And that visitor is an alien from another planet. I’m talking classic Grey. Humanoid with two arms and legs, a big head, two large black eyes, nostrils, and a mouth. Skinny too. One of the best parts of this movie is the phenomenal introduction to these creatures. I thought they’d be hidden from view for longer, but it works well. It’s an encounter, the alien isn’t trying to hide so the worry goes quickly from “What is that outside?” to “That’s not human and it is in the house, right by the stairs!”

The visitor is aggressively curious and Brynn wants nothing to do with that. It has wild telekinesis powers too, so there is a scary difference in strength despite Brynn being similar in height (my man clearly does not lift). So she manages the fight or flight response and survives the night, which is a wild time. In the morning, she makes it back into town to get help at the police station and that’s when the next layer of Brynn’s past is peeled back.

The movie deftly moves between and intertwines the mystery of her conflicted past and the mystery and danger of the alien invasion. Brynn is truly alone battling for her mind and body for the entire movie and it’s a harrowing experience. She’s constantly being chased, even when an alien isn’t around.

The action scenes are done well, I frequently found myself wide-eyed in anticipation. Brynn is a smart character who does logical things. She doesn’t get in trouble because of boneheaded decisions that were written to create inorganic danger and tension. While the CGI is mostly excellent, the lighting of the creatures frequently doesn’t match the scenery, so it’s obvious they’re digital. There are also mannerisms–the way the aliens communicate–that came off as really goofy to me. I definitely laughed when no laughs were intended, so that knocks down the spooky factor a few pegs. The sound design is 100% fantastic though, which helped suspend my disbelief when the visuals didn’t.

I’m on the fence about the ending. I thought I’d settle one way or the other, but days later from seeing the credits, I’m still not sure. It doesn’t ruin the movie, but I was hoping for more. I don’t think it reaches the highs of the rest of the movie.
