The concept was original, the cinematography was wonderful, the acting was stellar, the music was haunting. I remember seeing the American remake (The Lake House), but I could never forget that they were actors in a movie, because they were famous. This was completely different.

Though I've seen both of the main actors in other works, I was completely immersed in this story. Let's start with the locations, the architecture, the cinematography. The film was full of shades of blue, fog, mist, and water, all that gave the strong feeling of calm, quiet, and mystery. The house on the lake, I think anyone would want to live there. The house, far from everyone and everything, gave the feeling of loneliness, and to a certain, degree, depression. The character of Kim Eun Ju (Jun Ji Hyun) was just full of loneliness. She'd been unsuccessful in love, wasn't doing too well in moving on, and if I'm honest, a little irritating in that she wanted to hold on to her putz of a husband. Han Sung Hyun (Lee Jung Jae) gave off the vibe of a real loner. Someone told him early on that he needed to learn how to open his heart. He seemed perfectly content in his solitary life, yet something was missing.

The two communicate across time, and Sung Hyun even addressed the improbability in that Cola, the cutest dog ever, was in two places at once. We get to know these two better through their correspondence and I really hoped there would be a happy ending for them.

The haunting song, Must Say Goodbye, was played throughout this movie, sometimes instrumental, sometimes with words. It was beautiful and went perfectly with the movie.

I would probably not rewatch this movie, since I know what happens, but I would definitely recommend it. A warning, this is a slow movie. Not much happens, but in a world that seems to be moving at warp speed, it was nice to sit back and enjoy the slow ride.
