I have watched the first three episodes now. (Massive WoT nerd back in the day, it's how I met DH.)
I do NOT like how grim dark they've made it. I hate what they've done with Mat's family.
They certainly weren't subtle about the Whitecloaks (ep 2).
The books were a lot better on this, gave complexity to the organisation.
I am really glad that they've aged up the main 4. Will be good to have less teen angst. Please have less teen angst.
Missed Thom in Emond's Field. I thought they really needed him.
2nd and 3rd episodes were much better than the first. Ros Pike is growing on me, but despite her being a huge fan of the books I don't think she's quite managed to portray Moiraine properly.
Lan is great. Don't like their implication of a sexual relationship with the stupid bath-tub scene, though.
I have a lot of feelings. Overall, after three episodes I'm about 75% happy with it. Did not like the first episode, though, and if I hadn't been a fan of WoT I'm not sure I'd have continued with it.
