I don't mind films with narratives that are a bit vague and can be left open to interpretation by the viewer, but there is a limit, and for me this film went way over that limit. It set up compelling mystery after compelling mystery in the first 2 acts then ended abruptly with no answers to any of them. When the film ended I felt cheated, it was like the filmmakers had no idea how to answer any of the mysteries their film had set up in the first 2 acts so decided to not even bother trying and instead introduced even more mysteries into the 3rd act that were left unanswered as well.
I can think of at least half a dozen plot threads in this film that were left unanswered, and I don't just mean left open to interpretation by the viewer, but unanswered. That's not fun, that's not artsy, that's just plain good old fashioned poor storytelling. It's a shame because the first 2 acts that set everything up were so good.
