Phone (2002)

Soon after Ji-won gets a new cell phone, her friend's young daughter, Yeong-ju, puts it to her ear and immediately begins screaming in terror... Directed by Byeong-ki Ahn.
Korean spooky flick. ahhh, pretty stale material. The beginning seemed promising but it quickly made room for "plot" by getting rid of all the fun stuff. 5.5 out of 10, but still worth watching (barely).
