Connor Denney’s review published on Letterboxd:
There is more bare emotion in the pauses where we watch Blaire's text cursor blink as she tries to decide what to write, when she knows that her words may hurt someone she loves, than many films have over their entire runtime. More than simply making effective use of a gimmick invoking modern technology, the film explores how the digital reflects the personal, how our online experience is driven by the way we choose to interact with the tools and information available, and how that in turn has ramifications in the physical world. Where similar films deal with computers and the Internet as an experience in themselves, Unfriended shows it as more of a tool for developing real connections and relationships; its plot is about the misuse of such a tool. It's a very inventive film, but its inventiveness shouldn't mask the fact that it's also a pretty raw, aching film as well.
