The thing about TB's reviews, especially as he's matured as a writer, is that they first and foremost entertain the reader. Second, they give a view of the reviewer himself.
The first point is of obvious importance, especially in a review of the type of subject matter we're dealing with.
The second point may elude some. Knowing the reviewer's mind and attitude can give the reader an idea of whether he and the reviewer are on the same wavelength. If they click as far as the review is concerned, the possibility of them clicking in regards to what is being reviewed is greater. I don't have any empirical evidence to support this, but it seems intuitively obvious to me.
