Cem K.’s review published on Letterboxd :
A perfect movie for a calm evening. Beautiful cinematography combined with a touching story and an awesome ending.
Watching the trailer will give away the surprise element of it, so do not do that.
Also, don't expect a science fiction movie, as the name (or, if you've watched it despite my warning, the trailer) suggests —it's not scientific in any way. It's touching, it's dramatic, it makes you sad and happy at the same time and the ending keeps you puzzled for a split second.
It's good. The best movie I've seen this year.
