I had to think on this one for a bit, but in the end, I *REALLY* liked it.
I thought it had a lot to say about belonging, wanting to belong, "gatekeeping" -- for lack of a better word -- as well as paths and choices we take and make in life. (And for the conspiracy/tinfoilers--which I can be one, no shade--it could show a darker, hidden truth)
And, it's Nic Cage, where "every word of dialogue is spoken in either a whisper or a scream," for crying out loud.
I think this was Julian McMahon's next-to-last film. I didn't recognize him at first.
Definitely not for all tastes -- but I very much liked it.
