The Caller (2011)

Well, the movie starts as a slow burner, many may give up within 30 minutes of the movie. It only picks up after that and becomes an excellent thriller with wonderful plot twist towards the end, giving more details would mean taking away the surprise element from the viewer. This one goes in the lines of Frequency and Lake House and add the thriller element to this, and what you get is very good thriller which keeps you engaged post that thirty minutes till the very end. 

When you reach the end, you will realize that two plot lines are running at two different points in the same movie: one from beginning to end and the other end to the beginning. Though the time loop or quantum reality has been already used before, but mixing it with psychosis is something new and that makes this movie with brilliant concept a fantastic thriller! Coming to the plot which starts normal for the first 30 minutes, Mary (Rachelle Lefevre) moves in to an apartment complex in Puerto Rico to escape her abusive ex-husband who is none too happy about the divorce or the restraining order placed against him. Soon, she starts getting calls from a stranger, who identifies herself as Rose. Soon, Mary tries to avoid Rose's calls as she thinks they are irritating. 

 Slowly, the people whom Mary knows starts disappearing one by one, also Mary discovers the fact that Rose is from her past and is dead in the present. You need to see how the plot develops further and where it finally ends. This movie is a fresh breath in horror thriller genre. My rating is 8.5/10.
