Catherine Cantieri’s review published on Letterboxd :
One the one hand, it's a fairly predictable genre film. On the other, it gets a lot of things right, particularly the way high schoolers talk to each other. And while there's certainly nothing new about the "found footage" technique, it's rare that you see it employed so consistently and logically throughout the film. It really works here, both as a narrative technique and as an indication of the main character's distance from the rest of the world. I'd say this is one of the best films in the "teenagers get mad powers which lead to their destruction" genre.
