It tells the story of Henry Detrample (Eric Bana) as a librarian/time-traveler. He travels back and forth in time without being able to control himself. He can travel at anytime and anywhere. His life seems miserable until he met Clare Abshire (Rachel McAdams) one day. Clare recognized him as the time-traveler from the future who has come to meet her several times since she was six years old, although Henry himself has totally no idea about it. Then the story goes on. 

This movie revolves around their love story, how the time-travelling (the genetic anomaly, according to Henry and his doctor, Dr. Kendrick) affects their lives, how they still love each other despite the odds, and how they still trust each other with all the crazy things happening around them. 

Just like Rachel McAdams said in the interview, "Time traveling is...confusing", but I could ensure you that this movie won't puzzled you at all. The story is presented splendidly well, I didn't get confused at all. In fact, I was so immersed in the story. The story line is so unique, unpredictable and it's not boring at all. The director directed it well, the scriptwriter wrote the script superbly, and the casts played their characters gorgeously. Oh, one more thing! I even liked the settings in this movie: the meadow, their color details, even the snow!

Well, once again, I presented you another masterpiece! Totally recommended!
