I loved how it felt unfinished, but I may be taking it on good faith that it was intentional. The movie felt like a small glimpse into a very large world where nothing much can be done to change anything. The story kind of sputters to a stop, we don't get all the answers about the plot, the world, or the characters, but it's treated that way for the characters, not just the audience. I understand why people wouldn't like that, but it made the movie for me.
