Almost, but not quite entirely, unlike
the reaction of the reviewer I, to borrow Arthur's words, "actually quite liked it." I definitely agree that the author tried a bit too hard to write like Adams in the first few pages of the book, but "after a while the style settles down a bit and it begins to tell you things you really need to know". I wasn't looking for an in depth biography, it was the analysis and background to the work that interested me most.
I was somewhat horrified to learn for example, that the towel I bought from ZZ9 Plural Z Alpha on signing up as teen in 1983 (and paying a ridiculous amount for after conversion from sterling, and shipping all the way up here to NZ), was one of only a couple of thousand made. Now I sort of wish it didn't look quite so much like a 30 year old towel!
I think the book achieved what it set out to do, and the author made repeated references to the other biographies available, so that readers looking for a more familiar personal focus could find it elsewhere. I certainly don't regret buying it, and I think most fans would feel the same.
