Certainly not crap, as a writer he can really craft a line, but in recent years his craft has been undermined by the vacuousness of his ideas and his inability to engage with anything in a remotely interesting way. His views on Islam, as expressed thus far, have been utterly predictable and largely reactionary, symptomatic of a writer incapable of exploring the most important cultural theme of the present time.
In my humble opinion he has yet to write the novel which will fulfill, realise and encapsulate his potential.
