Even though it's been over 60 years since Bob Dylan arrived in the New York East Village Folk scene, his grip on American culture has never loosened (despite his best efforts). He started trying to zag when the culture expected him zig early, which is largely the subject of A Complete Unknown. This entry into the Movies About Bob Dylan sub-genre is helmed by writer/director/producer James Mangold, who has spent a career reinventing himself and avoiding labels as well.
