The 1/12 the data bit was equally annoying. If the heptapods needed our help in 3000 years, why the fuck would they split up the data needed to understand the language across the planet, only to want humanity to work together to achieve that goal??
Shouldn't they have just made it easier for humanity to understand? If Earth had gone into World War III against the Aliens, then the heptapods would be screwed. (presumably).
This is some Damon Lindelof shit right here. How is MC eating this up?
