The bad wigs and fluctuating accents are counteracted by Mary Harron's dream-like direction, and the emphasis on plot points rather than character development is occasionally shaken by some of the noteworthy performances (such as Virginia Madsen as Smith's hard-bitten mother).
Anna Nicole has an extraordinarily hazy point of view, tonally sympathetic to Smith but unwilling to explore any of the details, sloppy but particularizing, that might mitigate and humanize her increasingly terrible behavior.
