aritmetic mean serves this movie best!
i think the arithmetic mean is closer to the truth than the weighed one. this movie is quite funny, it doesn't bore you, the ending is nice. throughout the movie there are two memorable scenes: the lesbian party scene and the photos' scene near the end. overall this movie is better than other of its kind, and i agree that this subject is too frequent but this should not influence objectivity.
i give it a 7. i think 5.9 is too low. it should be arround 6.5, the way the arithmetic mean is.
