Definitely one of the best time travel / time loop movie I've watched in a long time. It really puts you at the edge of your seat. Park Shin-Hye and Jeon Jong Seo are both spectacular here. I just don't see this movie succeeding with anyone else aside from them.

It's always difficult to create a good time travel movie as there are just too many things to explain and it's really difficult to ensure everything is tied together. They did it pretty well here.

No doubt this is sort of a remake of the old English film but still, the actresses played it to perfection. You can feel the thrill when shin hye and Jong Seo were having their cat and mouse game and there's always that lingering question, how can someone from the present (A) prevent someone from the past (B) from killing A's past self, especially when A has no way of reaching her past self ?

It's like a totally against the odds tale. You know chances are extremely high that A is gonna lose, but you still want to find out if A can actually win.

Masterpiece really.
