This film deserves all ten stars, mostly because it's a legitimate and creative exploration of the Many Worlds interpretation of quantum foundations. It does so brilliantly, in my opinion, and from the very beginning. (Note : I would watch this without being spoiled, which I am about to do.)
The basic plot is that a comet causes "coherence" (i.e., the opposite of decoherence, which is a quantum mechanics phenomenon that some believe causes the world to "branch" into multiple different versions) which brings a large number of other worlds together. The guests at a dinner party encounter slightly different versions of themselves.
A watcher knowing nothing about the film (as I was originally) would not pick up on this, but the film establishes early on that it is set in a world alternate even to the viewer's world ("our" world). It does so by using an actor who most of us would recognize from Buffy the Vampire Slayer playing an actor who was not in Buffy, but was the lead in the show Roswell. (Roswell existed as a show in our world, but this actor was not the lead in Roswell.) As well, characters get small things wrong about each other from the jump, which in retrospect one realizes means that the worlds "cohered" even before the dinner guests arrived at their hosts' house. (The beginning of the coherence is depicted by the main character's phone cracking as the movie just begins, but the viewer only realizes that retrospectively, if at all.) This is ironic, because the guests ultimately realize that that there are other versions of themselves that are getting all mixed up and panic about it, even though they were mixed up from the jump and oblivious to it. It is this thoughtfulness (and playfulness) that forces me to give all the stars, even though I don't like doing that. Throughout the film, there are lots of subtle things happening and said which are easy to miss and reward repeat viewing.
It's also worth pointing out that there's an underlying emotional story here, too: a woman whose calling as a dancer was missed by chance and who uses the coherence as a way of taking back control. Or trying to...
On top of all this, the film is well acted and edited. I like a tight, 90-minute film.
