Now, after having viewed The Odyssey in both 70 mm and 4DX, I have my gods-given answer: This format is not for the faint of heart. The Odyssey in 4DX starts off incredibly calm. No, the 4DX experience is not a slapdash result of button-mashing on a video-game controller. Still, Kim emphasizes that the 4DX team “maintained the contrast” of Nolan’s films by having the action ramp up from practically nothing at the start, rather than throwing audiences in headfirst. “There’s no way we’re going to sit here in a three-hour movie about a boat on the ocean and have the water off!”
