"Life of Pi" is a case in point: just about the only thing you can say for certain about it is that it is fiercely and admirably unique. The plot, if that's the right word, concerns the oceanic wanderings of a lost boy, the young and eager Piscine Patel of the title (Pi). After a colourful and loving upbringing in gorgeously-hued India, the Muslim-Christian-animistic Pi sets off for a fresh start in Canada.
