Why Coherence is worth watching
Four couples gather for dinner the night a mysterious and powerful comet passes overhead.
Eight friends gather for dinner on the night Comet Miller passes Earth. Phones die, the power flickers, and a mysterious box appears on the doorstep — a cosmic joke that stops being funny fast.
When some guests walk to a house that looks exactly like theirs down the block, paranoia explodes. Every choice splits reality. Every mirror may hide a double who made a different decision.
James Ward Byrkit's Coherence is sci-fi as chamber thriller: one location, rising dread, and a puzzle that turns friendship into the most dangerous weapon in the room.
