I'm actually surprised there weren't any reviews for this film yet. It has a high score on Rotten Tomatoes.
I am not a very good writer the way other reviews are written, so I'll keep it simple:
As you can gather from the trailer, this is a story about an Icelandic man who appears to be reaching a point in his life where he wants to perhaps tie up some loose ends, which included searching for his long lost love. The love affair was set in the rebellious 60s, and featured the younger Kristoffer looking for a job in London while he was still studying abroad from his Icelandic home. He picked a Japanese restaurant because of the help wanted sign outside, but as he was leaving, he saw the restaurant owners daughter and decided he really wanted to work there haha. Well, you can't blame him, Miko, played by the very attractive Koki, has wonderful charisma, and she gave him that second look as she walked away lol. Well, you can sort of guess what happens with the whole dating the boss/father's daughter behind his back, then it's discovered. So the elder Kristoffer was hoping to reconnect with his lost love.
The movie is presented in chronological order, but it jumps back and forth between the present and past. We also get insight into certain stigmatisms that Japanese society can have, and how that affects one's upbringing and destiny.
Overall, it was a very well made film. I found all the actors (the younger and elder versions) very engaging. I was thinking at first this movie was about the young man becoming a better cook at the restaurant, but it's really about the relationship between Kristoffer and Miko.
And if you're worried that there's some sort of over the top, tragic ending, I can't spoil it for you - but you don't have to worry about that.
I hope more people go out to see this film and lend their better writing skills to reviewing this film and hopefully appreciation of it!
