Although the expositions are reasonably clear, Part 1 over-promises by squibbing discussion of scientific explanations for what came before the Big Bang, instead focusing on theories about the universe's early moments. The more often this happens, the further down the path of Deism I'm led.

Padded with a lot of (doubly) cheap drone-candy, other driving shots, and vox pops, at least it's mostly free of good-looking but not very informative animations.
