well this is my first review, so I hope I have put my views in a proper way
I decided to watch this movie because of park shin hye , as i expected she did not disappoint me and what came as bonus is the rest of the cast especially Jeon Jong Seo
As the plot says the story unfolds with a call but the call is not just all. The connection of the past, the present and the future reminds you of the butterfly effect.
The movie will always take u by surprise which is very needed in a thriller.
Their is dialogue where in Lee El tells her daughter that she is going to die many deaths in her life, u will not understand it in the starting but later u realize why said so and also u will understand why she did what she did. She is great mother and the actress did justice by her amazing acting
The background music when she (park shin hye) realizes that something happened is just awesome.
The ending is kind off a cliffhanger but its not a problem. If not anything it only gives hope for a second season
All in all its a decent movie to watch
