While I've read people complaining about RJ's female characters, it's not an opinion I hold. As a female reader, I actually appreciate the fact he put depth into his female characters, giving them flaws and moments of weakness as opposed to the token type females a lot of fantasy authors write in the genre. Same as his males to be honest. All the characters annoyed me at times, and I think that makes them feel more real. I like a lot of the females in the WOT. So, while RJ gets a lot of flack on that point, he's not getting that from me.
I felt like the series missed the mark on so many of the characters, IMO Nynaeve was not the character I came to love in the books among other changes that are more noticeable on reread. The series' take on Min was bizarre and unrecognizable. (I won't even get into the guys like Mat, Perrin, Thom, that would be it's own topic) The character changes probably bothered me the most, because the characters were the thing I liked best and they are what kept me hooked on the books the first time around. I didn't have the same attachment to the style of characters presented in the tv series.
While there are a lot of things I might have changed going forward, I don't see the WOT as all that hard to adapt within a series context. Some plots need cutting, a lot needs to be streamlined but ultimately, there are roads to take in that regard that wouldn't take the spirit of the story away. I feel like claiming the story is too difficult to adapt faithfully is just a handy excuse.
I'll agree to disagree on those points.
At the end of the day, the relationship between a book and reader leaves a lot open to personal interpretation and personal preference. So, that's why we're all going to walk away with different opinions and deal breakers when it comes to accepting an adaption, I think.
