Nynaeve's character was fine - her storyline was moronic. Whether it's the getting abducted by a Trolloc who just pulls her by her braid, or the way she then escapes from him unscathed, or her suddenly having Lan at swordpoint, or Lan tying her to a tree... In episode 4, it gets a lot better of course, but pity they needed to have so much nonsense before that.
They're going out of their way to show Egwene as a sympathetic friend - to Rand, to Perrin, to Nynaeve. Fair point about lacking her PoV in the first book, but then it's not so much in the first book that readers dislike her, but later on, I guess mainly from book 4 or 5 onwards.
Whatever critical reading skills one may or may not have, it's pretty clear that Egwene ends up being a very ambitious and rather self-centered person, who isn't much bothered about having to hurt or manipulate her friends as long as it serves her purpose. I do think that there are two main points to be made in her defense there, the first being her traumas from the Seanchan captivity (which, rumour has it, might be dropped from the series entirely) and the second the blatantly sexist way in which such naked ambition is tolerated in male leaders much more than in female ones. So considering all the discussion about just how 'woke' this series is, it would be interesting to see just how they depict Egwene in those later stages - perhaps I'm wrong and they would actually dare to keep her largely unchanged in those respects.
