The biggest problem you generally encounter when Hollywood tries to make a movie about rock musicians is the overwhelming tendency to dilute reality and surrender to the cheese factor. Honestly, filmmakers have gotten it right exactly twice: first with Rob Reiner’s This Is Spinal Tap – a work of blindingly brilliant satire – and later with Cameron Crowe’s Almost Famous; which, though a work of fiction, would be hard to top for its feeling of authenticity, in my opinion.
