I'm surprised at some of the negative reviews. I think they're thinking in terms of what makes a movie popular and successful at the box office, not what is successful in terms of a piece of literature or art. The narrative back story is subtle, not obvious. So if you're going to do social media on your phone while watching it, you're going to get bored or confused quite quickly. This one is like reading a book on the screen. They're not common but I loved the vibe. It's striking and doesn't over do the sci-fi elements as they paint the atmosphere, not the story. Acting is top notch. Some of these younger stars will be seen more of for sure. First thing I did after watching it was searching if it's a book.
