Unrealistic, at times, but managed to plod through. Anna's story was the most interesting, rather than "never step a foot wrong" Nick. He was too good to be true. Added to all this, how can a woman whose been on heroin for 5 years still be described as "so stunningly beautiful". The re-union of the two main characters towards the end, was such an anti climax, not what i'd been hoping for.
