This movie was on my Netflix watch list because of Park Shin Hye. I don't regret watching it. . .but if I'd never seen it then I also wouldn't be missing anything.

The film is about Kim Seo Yeon (Park Shin Hye) who finds a landline phone in her home and begins getting calls from a mysterious caller, Oh Young Sook. Seo Yeon figures out that Young Sook is about 20 years in the past and the two begin conversing regularly. Seo Yeon soon realizes that Young Sook's timeline is close to when she loses her beloved father. In a quick reversal of fate, Young Sook ends up changing the past by saving Seo Yeon's father. Unfortunately, this one good deed becomes a catalyst in which life begins changing drastically for both girls when Seo Yeon warns Young Sook of an event pertaining to Young Sook's own lifespan. Seo Yeon learns too late that her revealing of future knowledge will have dire consequences for her and the people she loves.

I think the movie took a different route with time alterations. Instead of parallel universes being created with shifts in past events, this movie shows us how the changes happen in "real time." The story had an interesting concept and the acting was top-notch. Big praises are deserved for both Park Shin Hye and Jeon Jong Seo. Both were marvelous and definitely are at the top of their game. The biggest fault for me was the character of Kim Seo Yeon. She is frustratingly ignorant. One would think she would have reservations on how much information she was willing to divulge to someone in the past. . .but no. Her motivations were selfish and the consequences backfired on her big time. To save one life meant she unknowingly caused the death of so many others. My biggest problem with her is that she doesn't learn from her mistakes. When they are at odds, Seo Yeon continuously reveals her hand and basically serves her loved ones on silver platters to the monster she unleashed . . . she really only made one smart decision yet even that backfired on her.

If you need something to watch on a Friday, check this movie out. The story is interesting and the acting stellar but like me, you may find the protagonist a bit too frustrating to the point of wanting to rip your hair out while watching her fail to protect her loved ones.
