All in all not a bad movie.
It is in some part more an artsy movie with brilliantly done colour schemes and atmosphere. Some scenes were too artsy for my taste and distracted from the story. However, these beautiful to watch setups made up for the somewhat lacking storyline and gaping plot holes. I really liked the music that enhanced the atmosphere.
The storyline is all over the place and at several points you have no idea why the characters ended up at a certain place or in a certein situation. Maybe the script was shortened, but it is kind of annoying not to know how a situation came about. Some scenes are really cute and are worth watching (e.g. the swing).
The acting was mediocre in my opinion, not bad, but sometimes a bit flat. Of course, the script did not help. The characters - even though their stories are interesting to start with - lack depth and inner conflict, changes come to suddenly you have to little contemplation and development.

Personally, I do not like that kind of ending, but it is not dreadful.
I am okay with watching the movie once, but I won't watch it again.
