If you have an affinity for mind-bending riffs on quantum physics, you'll enjoy "Coherence." Most of these types of stories take the concepts of quantum mechanics (entanglement, superposition, etc.) which exist at the most microscopic--level (electrons, particles) and posit that similar effects could happen at the macro-level (real-world people and physical objects). "Coherence" takes a nightmare dinner party scenario (ala "The Invitation") and applies the quantum concept of coherence and "many-worlds interpretation" (or multiple universes) that is triggered by a passing comet. It's better to come into this with as little info as possible to enjoy the unwinding of the mystery. While its a bit of a slow burn at first, the filmmakers really nail the ending.

**Overall : The greatest movie you've never heard of.** Coherence kept popping up on lists of best sci-fi films which was surprising because I had never seen a trailer or heard anything about it. I found it free to stream somewhere, so I checked it out, and I am so glad I did! What I found was a very low-budget film with a cast you have never heard of but a premise and script that were so well executed that this movie blew my mind! The panic and anxiety of the characters as they try to understand what is happening around them is told with such brilliance that the audience is lost, intrigued, overwhelmed, and bought in all at the same time. I'm telling you - watch this movie!
