Have now read the other thread AND this one.
I was a bit annoyed about the Perrin/Matt changes but actually, Perrin's one makes sense now because of course all the inner dialogue is a bit tricky so this neatly ties that up. I'm still not wild about Matt. I think they could have gone with him being extremely poor/constantly having to use wits and luck to survive, but the extreme of the portrayal meant that he doesn't seem light at ALL. If you hadn't read the books you'd have no idea.
Rand and Egwene shagging and so in love didn't work for me. I know he'd always expected to marry her but in the books my sense was always that it was an expected thing and they were good friends ,not a major love affair.
I didn't like the idea of Rand's 3 wives in the books but I loved all three characters and their relationship with him so I sucked it up. I'd choose Aviendha if I had to choose just one!
I think Nynaeve is 100% true to character, including her loathing and complicated relationship with Moiraine.
The only thing for me is that for some reason, I always had her in my head as as sort of buxom blonde whose skills, steely determination etc was in direct contrast to how people saw her at first glance. Was that just me or did I actually get that from the book!?
Perrin's casting is brilliant. Rand is not bad but he's a smidge geeky - but I can totally see him in his dragon uniform in a few seasons so.... Rosamunde is doing a surprisingly good job except that in the books it was so easy to think in the early ones that she didn't care, while it's clear that she does in episodes 1-3.
Possibly I've given all of this too much thought so far? My main thing is it's making me want to reread the series. For all the length of the books is challenging, I always loved the detail which you just can't get in a tv show.
