It's visually interesting.
The soundtrack, what I would call modern classical, is really strong .... if you like that kind of thing. I'm buying the soundtrack on BandCamp.
It unfolds slowly, in a way that was interesting to me, but that may be too slow for some viewers.
The last act left me, not confused, but somewhat dissatisfied. From my point of view it didn't really come to a conclusion. It may work fine for more experienced sci-fi viewers, but the ending was the weakest part of the movie for me.
I'm giving it three stars, although it may deserve four.
