The decision was made by the filmmakers to move the movie away of the previous "found footage" tropes (such as the use of a framing device, a linear narrative and a non-recognizable cast) and into a story "told through cameras that exist in the world of the characters" much like Chronicle. This is demonstrated throughout, including the deliberate absence of a framing device, the use of an animated opening quote, a recognizable cast, a non-chronological narrative structure and a final music cue that is playing in the taxi becomes the end-credits song.
