I really hope it is not the case. Do you really believe it is that bad? I've thought that at least the outline of Rand's and Egwene's confrontation was in the notes. I've made a number of fairly critical remarks about the writing of the new books, but I wouldn't have thought the major point of the plot could be made up on the spot by Brandon, without serious consideration.
If you listen to the Fantasy Faction interview, Brandon speaks about his method of writing a first draft and he states, essentially, that he writes it just with plot points in mind, and later goes back and edits for prose and character work and so forth. This is how he can churn out a 400,000 word novel in a year, but it does not leave time for 'serious consideration', and the short breadth of the edit period (which has been acknowledged directly by Team Jordan) doesn't lend itself to the post-production polish... all of which means, yes I do believe that lowest common denominator plotting is occuring.
I mean think about it, say the notes state: 'Rand goes to Tar Valon after Dragonmount and meets Egwene, who grows angry with him over his plan for the seals', which based on Brandon's own comments is about as far as the notes on scenes that Jordan hadn't written would go. Which is precisely what that scene reads like--indeed, instead of saying that Brandon has 'made it up on the spot', it might be a fairer criticism to say he wrote too specifically to the notes. Instead of developing specific, character driven nuance to hold the argument, we have a dumbed down Egwene sticking tenaciously to a non-specific last minute throw in dream, and an aloof Rand no bothering to explain his logic, or even gesture to the existence of it in order to allow the pretense of anger where, under the circumstances there should be none.
Nor is this the only occurence--in fact, to one degree or another I believe the vast majority of the plot work suffers from this. Take Graendal's attack on Perrin, for instance. It reminds me of the thing about keeping a five year old advisor, and not doing anything they could think of. Instead the feel is clear--Graendal needed to lose to Perrin--rather then figuring out how to get to that point in a way consistent to both characters, he simply made one dumb, enabling the other to attain victory.
And yet I thoroughly loved TofM the first time I read it. I think it is because it holds both plot-gratification and fan gratification--by which I mean he hits the plot points, and plays to fan expectations and desires, and so Egwene is all clever and bad-ass when dealing with the Aes Sedai, who are dumb foolish nitwits back, allowing Egwene to show them up in a way that is satisfying to the fans... right up until she meets with Rand, who stands higher in fan esteem, and therefore she becomes dumb herself allowing Rand to show her up, and gratify the fans. Same goes with that meeting with Perrin and the dumb trick with the ropes...
This method enables fast production, the hitting of the plot points, and a feel of gratification for the fans. It does not permit polish or nuance, and to some degree actively undercuts character work. At least in my opinion. And that's were I'll cut myself off and stop ranting. Feel free to tear it apart. Certainly I know there are those who are grateful just to learn what happens--I was also, incredibly so, and initially I had a very positive response to his works. But as more and more time passes, and the high brought on by the new plot information fades, I find I struggle more and more with tGS and TofM. I genuinely like Brandon--he's wonderful, and has always been nice to me... but yeah. I struggle. Sorry. :(
That pretty much sums it up...Brandon is a brilliant writer...I love his other works...but this is so big and he's under so much pressure to get it done that he just can't take the time to make it perfect...so he's making it the best he can under the circumstances.
