I just find the exerpts I saw (and I saw several) a little boring and samey. Having seen - and enjoyed - the Borat skits in the Ali G series, I think a whole movie of more of the same will be at risk from the standard " The Movie" syndrome, i.e. you can only repeat so many variations of the same joke. Indeed some reviews I read seem to confirm this; and the same happend with "Ali G In Da House".

As regards making fun of Kazhakstanis, those who believe Borat does so are missing the point: I take Borat to be taking the piss out of all those who would readily accept that this is how Kashakstanis really are. Of course this is not the case, yet he seems to find so many victims ready to accept him for real. When then the tables turn on them, some get angry - but for my money the real joke was on them the minute they accepted him as a bona fide individual.

A great idea for a joke - but in the end it is just one joke.
