@Bohnjaggs i helped explain to my dad why we should see it in the 70mm by saying this... a standard film is probably around 4K today (film technically has no resolution but for now lets just say 35mm is 4K), and he was blown away when first seeing a 5K tv at a hifi store... 70mm IMAX is basically 16K resolution..
but you'll have to fandango your ticket because they are in high demand
