Good movies can sometimes give off a hum—a feeling that the energy and chemistry on screen can't be constrained by the edges of the frame. Tangerine fits this description and then some, creating a kinetic rush with enough spillover juice to light up LA for a year. While chock-full of innovations both welcome (a story about transgender characters, played by transgender performers) and potentially eye-strainingly worrisome (the movie was shot entirely on tricked-out, stabilized iPhones), the main takeaway is just how alive it seems.
