A mind-bending and very entertaining independent science-fiction film, Coherence takes place over a single night in which a group of old friends (an ex-lovers) gather for a party on a night when a comet is expected to pass unusually close to the Earth. One of which is played by Nicholas Brendon of Buffy the Vampire Slayer in a scene-stealing role. I missed him.
At first, glasses start breaking and cellphones shatter. Then the power goes off, except at one house down the street. Then there are strange bangs on the door and bizarre notes left at the house. Things get stranger when two of them decide to go to the lit-up house to make a phone call.
It's a good film to me because the science-fiction concept ends up reflecting the real-life conflicts between the characters in a very clever way. I'm still not sure how I feel about the ending, but the film is a wild and entertaining ride before it gets there. Scenes propel themselves to other scenes with fast and snappy dialogue. Though it will be compared to films like Primer and Timecrimes, it's a pretty original film overall.
