I bought myself the book for Christmas. I still haven't had time to go through it really properly, but I do have some thoughts.
In a sense I possibly know what Bulldog means, since it does look as though there's often more emphasis on kingside action than on centre-transformation strategy. Maybe I'm being over-schematic but I always thought of the latter as 'the' main strategic idea behind the Botvinnik (against ...e5): specifically, exf5 followed by d3-d4 changing the structure to White's advantage. Maybe the emphasis, such as it is, on kingside play reflects Williams' style?
The book's upholding of the Botvinnik formation against '...c5 without ...e5' setups from Black did make me wonder whether theory had changed its mind on this at all, since the Botvinnik against ...c5 has often been regarded as solid but less impressive than against ...e5. If there's any new thinking here the book doesn't mention it. If Black goes for a KID setup with ...g6/..d6/...Nf6 I still prefer to meet it with a system Tony Kosten has commended on here, namely e3/Nge2 intending d2-d4, which scores well in my database. You can play this against a KID formation whatever, I guess (Ghaem Maghami seems to be the main specialist); if you know your opponent will play the KID, you can even play d4 on move one!

All this said, I do think AOC's point is relevant here -- I find the book's organisation rather confusing, but a lot of lines do receive some pretty thorough coverage, even if (inevitably given the target readership) not on the Marin scale.
