This show was a wild ride from start to finish. The writers did a great job in story telling for this amazing show which I'm sure was difficult with the back and forth between timelines and events changing, having to avoid obvious paradoxes along the way. I was riveted by this show. It was so intense the entire run. And while there were certain events I would have liked to have seen....well, it's a good thing I'm not the writer, because the scenes were perfect as written and more poignant than what I would have imagined. I also loved that the ending could possibly leave way for a sequel, and I would love it if they could bring back the three main actors to do it. But only if they could come up with another story as amazing as this one. It packed a lot of emotional punch.

The acting by our 3 main cast members was stellar. I thought that the boy that played a young Hae Young as well as the boy that played his hyung, Sun Woo have a bright future ahead of them. Little Hae Young was heartbreaking. The main villain was believably evil. One episode in particular had me yelling at him and on the edge of my seat in suspense.

I really liked the theme song and will be searching for that, as it just had a haunting quality about it that I enjoyed.

Even though some of the suspense may be gone now, I still think this show could be re-watched and still enjoyed nearly as thoroughly as the first time.
