The show's leap from 1945 to 1954—precisely the period when comic book sales were at their peak—is frustrating. For a useful corrective, I recommend Jean-Paul Gabilliet's finely detailed and important Of Comics and Men (2009).
Most shockingly, this second episode does not in any way explore the controversies surrounding the Marvel method of comics production and the disputed credits for seminal Marvel comics. Scriptwriter-editor Stan Lee is allowed to present, undiluted and unchallenged, what has become his official mythology of solo creation. Artists Jack Kirby and Steve Ditko are noted but briefly, as the hands who, the narration implies, drew up Lee's stories. Though there is some tasty montage work with images by Ditko and Kirby, the vital contributions of these two Marvel co-founders are undersold to a dismaying degree. Besides a brief encomium by artist Walter Simonson, the episode give almost no mention of Kirby's barnstorming creativity, design sense, and crucial input into marquee characters and classic series. Simonson is onscreen long enough to tell us that Kirby was the watershed, the artist after whom everything for the genre changed, but what Kirby's innovations consisted of, design-wise, idea-wise, story-wise, is never explained (in contrast to the extended treatment given to particular pages by Steranko). No single work by Kirby or Ditko is discussed in detail, nor is Kirby's widening of the genre's scope ever explained. Lee gets much screen time to repeat what have become standard stories about Marvel's rise (stories now widely understood to be highly selective if not self-aggrandizing). No balancing perspective is offered.
