If you loved Immersion, try Flight 7500
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Takashi Shimizu, and they sit in Horror / Mystery territory. If that's the register that drew you to Immersion, the second film will land in a comparable space — through a different lens.
What Flight 7500 is
Over the Pacific at midnight, a single overhead light flickers. Some passengers wake to whispers, others to vanished seatmates. A cabin fever dream spreads faster than turbulence. Japanese horror trades daylight for dark corridors.
