I don't frown about it. For what it wants to be it is good enough: an introduction. I just don't agree with this:

According to McDonald it is necessary for all Dutch Classical players to know the transpositional possibilities into the Stonewall.
In general I am opposed to studying many subjects at the same time. It leads to superficiality and perhaps even confusion. I have been playing the Iljin-Zjenevsky for more than 10 years and only now expand my horizon with the ...Bb4 variations.
The point is this. McDonald is a GM. I am not, my Dutch OTB-rating is about 1800. So opening knowledge for me has other demands than for McDonald. I am very sure that on McDonald's level a detailed understanding of all the transpositions and choices is mandatory.
But for me? I play f5, Nf6, e6, Be7, 0-0, d6 in some move order, then decide between ...Ne4, Nc6, a5 or Qe8. I know that it is my task to develop my Queen's wing and to prepare ...e5. Also I have analysed the critical lines as good as I can.
Keith Hayward earned titles both in OTB- and corr. chess with this approach.
You might play quickly through the games of the McDonald book. Then decide what setup you like best and make a thorough study of that one. If it's not the Stonewall I - and a few others - may help you pointing at the critical lines. If it will be the Stonewall there will be other others.
