It's been over an hour since I finished the film. Verdict? Even if you know the ending, it still unsettles. Having accidentally read about the film's conclusion in advance, It's a credit to Michael Tolkin as writer and director that he pulls off a high level theological thriller that actually dares to provide answers.
Firstly, anyone going into the film would be best advised to jettison their baggage. It's not that type of film. Though no doubt that liberal secularists will be incensed thath the film doesn't conform to progressive liberal tenets. Good. Hence, going to the film with no axe to grind will leave you clear to think about its conclusion. (Film's conclusion does bear a resemblance to another film made many years later. I won't name the film for fear of spoiling both.)
Secondly, Tolkin creates an atmospheric feel and tone which fits the subject matter and issues at hand. Thomas Newman's soundtrack is one of the best he's done. It lends itself.
Thirdly, performances. All concerned, not least Mimi Rogers and David Duchovny give two of their best performances. Especially remarkable given how Tolkin is a first time writer and director.
Finally, forgive me if the film comes across as the type of thing where the less you know about it the better. But it is difficult to write about it in specifics without giving anything away. Suffice to say, watch the film with no preconceptions. Draw your own conclusions. In short, it's impressive.
