I've watched episodes 3 and 4.
The one thing that sticks out to me like a sore thumb (really) is the absolute down to the last detail perfection of the women's faces. There is not a single imperfection in texture or color, to such an extent that it looks completely unnatural and Barbie-like. Even when in the middle of a huge forest, travelling for several days, everyone, and especially the women, just stay pretty and perfect.
In the end, up until now, the series is OK with the possibility of becoming good, if you keep in mind that it's targeted at current day teenagers and if you DON'T compare it to the actual book.
