Why did someone need to say it, we all knew what it meant! Temporal fissure sounds more scientific and intriguing (and potentially more painful
) and leaves it a little more mysterious and open ended - it clearly hints at some sort of time traversing, but maybe done in a way we haven't really seen before - which is exactly what the film delivers. Anyway, why this need to have everything 100% spelled out at the start of the film? At the start of Raiders do you want Indy to say "If you open the Ark everyone will either set on fire or their heads will explode, deflate or melt!"
