The director is completely clueless of what to do for the final 15 odd minutes of the movie. He can't kill Manju warrier because she is the heroine. Some how the director also decided it's not fair to kill those who assist her. Nevertheless a good attempt in creating a harmless horror movie. I won't say it's a time waste movie, you may not regret watching it once. A couple more body count would have made the phone villian appear serious.
