There's something really honest and quirky in the acting on the parts of all the major characters. I found that really appealing. The story was a bit hard to follow at the beginning, but that's typical of European film, I think - they don't exactly go for the North American journalistic approach. Most European movies I've seen have had the story unfold and develop without many overt clues as to what's coming later. The plot development seems much more subtle. I happen to love that.
The direction was really cool too... There were a lot of overhead shots, and some unorthodox angles in the camerawork. It made the movie more enjoyable to watch... at least for me, anyway. I wish I could have seen a little bit more character development in two of the three couples featured in the film, but I can also appreciate the open ending that leaves me to make my own decisions about how the characters ended up after the film.
I saw a similar film called Turn Left, Turn Right - it's Chinese and sort of follows the same concept. So, if you're looking for a similar story with fewer stories to follow and a little more closure, check that one out.
