Your opinion of this film probably does depend on if you've read the book. I did read it and to be honest didn't love it but nearly everything I did like is missing from the film. Firstly the Britt in the book was far more disfuntional and clueless but this was what drew you to her and made you like her. Then the next best thing was her relationship and reliance on the person who arranged the job that she took. This was such a pivotal part of the story that it would be like making a film of the Titanic but never mentioning that it's a boat. I realise you cannot use everything that's in a book but to leave such an important part where so much of the humour came from is such an own goal it's ludicrous. What your left with is a film that is very serviceable and workman like but with very little else.
