Ever since I read Jean Stein's fascinating biography "Edie" some 15 years ago, I've been waiting and hoping for somebody to take on this subject. And while this film does have one major disappointment (the inability to credit the Bob Dylan character as actually being Bob Dylan) Sienna Miller's performance is downright scary in it's authenticity. She completely channels Edie Sedgewick in her appearance, her voice, her spirit - it is very apparent that Ms. Miller did her homework and aced the final. In capturing that era of decadence and emotional squalor this film seems eerily precise, and it draws a very unflattering (but I think accurate) portrait of the Factory scene and Andy Warhol's role as a benign but sadistic manipulator of some very damaged people. Like it's subject, this film is sometimes hard to handle, but it has a lot to say about the nature of money, power and fame, and why having all three isn't all it's cracked up to be.
