On Hanif Kureishi's works, follow-up

I finally read (and watched) other works by Hanif Kureishi which I find much more interesting than what I've been reading so far : The Black Album (book) and My Son The Fanatic (movie, adaptated from one of his short stories). It's essentially about the same subjects : a young student coming from an sub-continental family living in England, muslim «but open-minded and well integrated», experiencing a great sense of bewilderment, lost betwen two worlds (the religious one, typically made up from young adults looking for their «roots» as a reaction to the racism they're subject to, and the liberal world made up by «white» english people with «loose morals», intellectuals and revolutionaries ranging from the drug dealers to the university professors). The book is more about the point of view of the son, whereas the movie is more about the father's point of view, watching his son turning from a «average» boy to a «fanatic». The son in the book ends up choosing the liberal world while the son in the movie goes definitely fanatic and leaves the house (as do the mother, leaving the father alone with his english girlfriend). Though I'm not entirely convinced of both works, the characters are convincing, real-looking. The only bad critic I would make is about the plots themselves, which do not allow any space to the majority «in between» worlds, theses worlds where english people might be white but conservative on many things, where immigrants and their children might be both midly religious and liberal on many things, all these «in between» reflecting the negociation ground in the life of so many people who have not and don't want to choose either of the «absolute» worlds he describes (the totally liberal one and the fanatic one). It's as if these middle grounds don't exist in his fictions, when anyone's day to day experience shows that they concern the majority of people ...  But then I guess they were works of their times, following the Rushdie Episode and all this, and above all knowing that a plot evolving between fanatics and liberals is much more appealing to audiences. But that doesn't mean these work don't represent some realities (otherwise the characters wouldn't be convincing), it is just only showing a very small part of the reality ...
