If you have read the book - do not set your hopes high, if you have not - go read it, and never watch the film. It is strange to learn that Toby Young was actually involved a lot in the writing of the script (as he claims himself in the post script of the book). Because the film is very different from the book.What the film seems to be aiming at - taking a rather thought provoking and entertaining piece that combines philosophical ideas with plain funny sarcasm and simplifying it so that everyone would understand it - it achieves with perfection. The film is full of bad and cheap jokes suitable for a sitcoms, and has lost any meaningful message that it could have had.You are better off not seeing it.
