Atmospheric, mysterious, somber, oblique, apocalyptic. Goes needlessly off the rails a bit when hallucinogens are introduced in that always-disappointing way which has the filmmaker apparently thinking that gas lighting the viewer into wondering what is real and what is a hallucination is somehow entertaining or clever. It's similar to movies in which something creepy or startling happens but, oh gee, it was just a dream. These tactics are ineffective cliches and almost always bring a movie down a notch or two in my book. Despite these shortcomings this is a pretty cool movie with an impactful inclusion. It does come down to literally the last 30 seconds, in which we see that a stylistic element that had been introduced earlier in the film as seemingly a mere stylistic element is actually part of the story.
Side note: I have to wonder whether the name of one of the antagonists being Belasco is a nod to The Legend of Hell House, the Richard Matheson novel, and if a reference to Beaumont Street is a nod to Charles Beaumont, who wrote some of the best Twilight Zone episodes. This movie does have a very Twilight Zoney feel to it so maybe it's not a coincidence.
