I entered The Public Image is Rotten, a portrait of Sex Pistols’ frontman Johnny Rotten (John Lydon), not knowing exactly what to expect. Frankly, it is how I approach all musical documentaries – I feel like the less one knows about the subject the better. In the past, this exercise has served me well – that is watching documentaries on folks I may not know and whose music I cannot pretend to listen to. It is a fun project, a musical journey of sorts in which I venture into a musical arena I may not have otherwise explored.
