Actually, the real problem with Factory Girl isn't just that it's a horrendously unwatchable piece of shit. (If I can't even enjoy seeing Sienna Miller nude, the movie is doing everything wrong.) It isn't even that it demonizes Warhol or that it champions stupid folkie piety. It's that it ludicrously ignores the popular mythology (and possible fact) that in 1966 Bob Dylan was doing more speed than the entire Warhol factory combined. That and it has Hayden Christensen playing him. I eagerly await the casting of Jarvis Cocker as Alvin the Chipmunk.
