Yeah, it's a slow movie. Doesn't make it bad tho...
In my view, this is a good mix between The Invention of Lying (2009) and God Bless America (2012).
The story is pretty good - it throws out of the window some of the conceptions we have about the world (like women being picky or everyone gunning for a CFO position). And it's kinda unexpected that the world really ends (which is good) so you don't have to see last minute salvations - Armageddon anyone?
