Firstly, there is no argument that this is a classic of the genre and a useful read for GP trainers and those interested in the consultation. There are distinct useful themes for discussion, consultation analysis and teaching.
The downside is it is a heavy read and written as an academic next so lacks the informal style of, say, Neighbour or Tate.
For those reading for nMRCGP or for personal interest there is a frustration that practicing as suggetsed is not feasible in a ten minute slot and the idea of perfection makes this less useful in real life. Nonetheless it can be used when analysing difficult cases to identify exactly where problems lie for future improvement.
In short for some of us this book is a necessary evil, for others a useful academic reference and if used correctly a tool for analysing and improving consultations.
