Just so we're straight there.
I really don't see what your point is.
Let me clarify for you in very simple language:
It's a matter of fact that NG has been on the Amaz*n payroll. He's had more than one of his
books adapted for TV by Amaz*n and others adapted for audiobooks by them. Amaz*n pay him for that, hence he's been on their payroll. This is in no way a criticism of NG, it's simply a matter of fact that he has been paid by them for adapting his work.
It's not good business sense to appear critical of a company that you may wish to do business with again in the future. So when he's asked directly what he thinks of
RoP he has to be diplomatic in his response,
whatever he might think of it. Here says that it's a "fun" TV series that he would have liked to watch as a kid.
In my opinion, to say that an (allegedly) serious fantasy epic that is costing many millions of dollars is, effectively, 'kid's stuff' is damning with faint praise. Of course, this is only my interpretation. But it's a very interesting use of words by NG, don't you think? A well-respected author of many, many fantasy
novels didn't say it's the sort of thing he'd watch now, as an adult - he said it's what he'd watch as a kid. Draw your own conclusions.
It's worthing noting at this point how much Amazon have riding on this "kid's stuff"
But I guess some people are going to love anything with the LotR label attached to it, no matter how dreadful it is. Enjoy!
