Things become so wierd when a group of friends gathered in a special night at which a comet passes.
Coherence is a science fictional movie with some thriller component.This is the first thriller movie I have ever seen.It talks about a story about,as the title noticed,the coherence of different parallel universes.A cross suddenly appears when the comet passes,thus people from different universes can easily go into another universe,which lead to panic and chaos.In the end of this movie,the heroine chooses a perfect world,then killed herself in that world to take her place.
Coherence is more likely to be a philosophy movie than a science movie.It is talking us a story about human nature that when emergency occurs,the dark side of human beings.This coherence gives our characters an oppotunity to have a glance of their life after different choice,thus they can get a touch with another life.
