The concept is similar to Frequency (2000), where 2 people from the past and future can talk across time, on Frequency using radio, and on the Call using a cell phone. And I can't help myself comparing the two even though the stories are different but there are some that are similar.

The Call is honestly got its story very well structured. The first half pretty much binds me to the characters; The second half brought my emotions up and down with its drama but to be honest, I'm already bored with drama material from South Korea, it's still effective but now I'm starting to dislike it. The third half starts to become pure thriller, then hmm ... okay, until here I realized, I have to start watching less Korean films.

So in the end, I got mixed feelings, I neither love it or hate it, but sure this is worth to watch.
