The weakest part of the show is the dialogue, which is often tonally inconsistant not only with the movie it is based on, and but even with itself. Even some of the more clever lines are tonally inconsistent and pull me out of my fantasy epic. This was at its worst in the first episode which focused so much on the several youths talking the way Hollywood writers would write modern day teenagers (I say "youths" because by the timeline aren't they supposed to be in their mid-to-late 20s?). It hasn't been as bad by comparison in subsequent episodes because the mix of characters got less pseudo-teen-centric once the quest began, but this most recent episode (four) was a bit more characters-sharing-conversations-heavy, and it was a step down from episodes 2 and 3 which basically just worked for me, with minor quibbles.
I don't think the writing on the whole is bad, because there is more to writing than just dialogue. The story and character beats are mostly pretty good, and I at least kind of like the characters. The episodes have all ended making me want to watch another episode. And, once again, I think some of the lines that bother me are actually funny, or cleverly written, or whatever; they just don't strike a consistent tone for the series, and pull me out of it. And other than one woodswoman not having any combat sense, and a bit too much retreading of tired teen-angst tropes that I just never really enjoy, everything that has bothered me in this series has ultimately boiled down to awkward dialogue.
