Not Everyone is in Close Proximity to Professional or Semi-Professional "Theatre", this one has "Off-Broadway" Written all over it, therefore the Movies can Offer Audiences want to Experience that sort of Thing, at least "Two Dimensionally".
This Film Looks, Talks, and Plays Out like a Stage Play. Early Television had things like "Playhouse 90" and this Story and Production would Fit Nicely in that Format. The Writing is Sharp, Ambiguous, Mysterious, Attracting, and sometimes even Profound.
The Acting is Uniform and the Two Leads (Rachel Weisz, Michael Shannon) do Their Best Weaving In and Out of the Complicated Scenario. It's one of those that if You Pay Attention, can Draw You into its Maze as the Twists and Turns will Hopefully Lead to a Reward.
Reaching the End of the Puzzle that is "Alice" is Semi-Rewarding and the Jigsaw like Journey does Unveil slightly Disturbing Behavior and is Meant to Question Commitment vs Freedom.
But Life's Important Decisions are so Multi-Layered and Complex that the Easy Answer of just "Moving On" every Year or so is Hardly the Solution to a Varied and Fulfilling Life.
This is Obviously Reflected on "Alice's" Face and Demeanor as She Relates Her Biography and after Her "Confessions/Revelations", She is right Back Where She Started, just like a Rat/Robot going through the Maze Again and Again with Little or No Lasting Reward for Her Efforts.
This is for a Limited Audience, certainly Not for Everyone, but Recommended for those that like Their Movies with More Head than Heart.
