And best of all a true fan understands the infinite allusions and illusions of the book. Consider just one example. In the book, the rich baby turns poor and the poor rich, in one simple swap. The Hindu kid becomes Muslim and vice versa and it is the good intentioned but stupid Christian that intertwines their fate only to make them enemies for life.
If you see it as a religious and nationalistic metaphor you'll see the perfect allegory for India, Pakistan and their relationship with the British Empire that created and thus entwined them in hatred forever.
A true fan also understands how in oblique ways, Midnight's Children has been the fountainhead for many other wonderful works of art - books, movies, graphic novels, etc. Again sample just one, admittedly silly and simplistic example to understand this. Those who have read the graphic novel Watchmen will not fail to see the similarity between the two books. Both about superheroes with naively foolish 'good' superheroes, pitted against the intelligent and scheming and extremely powerful bad superhero.
