Gets lost in the backroads of circularity. The 1st half establishes its Twilight Zone-conceit, then the rest tries to complicate it with adding another character into it, and thus, reveals itself as a sort of self-actualization journey. Yet, that's not even made too clear, since it still has far too much mystery, as the characters are not defined outside of these devices. And did I mention it was very repetitive?
Reminds me of a film called The Reeds in that it's an outside-average cum-horror film that takes place in a labyrinthine locale and was made with an apparent low budget, recommended if you've seen the classics and want to ignore the cliche-ridden Hollywood blockbusters.
