The movie was extremely funny although parts make you feel uncomfortable it was better than the TV show Ali-G (Bruno segments).
Sacha is a wonderful actor it takes great chutzpah to get into some of these situations that he does. Parts are staged parts are real interviews/interactions with people in the "real world" and the inability for the audience to differentiate between the two shows how creative the movie is.
This fell slightly short of Borat but not by much. You will leave the theatre laughing and feeling guilty that you think it is so funny.
