Its not a great film but it will keep you entertained from start to finish.
Even though its meant to be a comedy the funny moments are few and far between. The single largest strenght of this film is Ricky Gervais, he manages to turn boring situations into quite funny ones and he reminded me a bit of John Cleese. That said Ricky Gervais is a good comedian but his acting could do with some work.
Overall the film did what it is meant to and kept you interested but its not going to win any awards and certainly is not an unmissable film.
