In a previous post I mentioned Christopher Skinner's book, Reading John (Cascade, 2015). This doesn't happen often with books on the Bible, but Reading John: The Movie has been released online. Not since Mel Gibson's The Passion of the Christ has the big screen seemed too small for its subject.
In all seriousness, I repeat my recommendation of Reading John for anyone interested in diving into the Gospel according to John but unsure where to begin. There's lots to dialogue with here; Skinner makes observations both interesting and controversial (does he really say you can't say anything about the New Testament until you've accounted for John's Jesus?!), and always with the heart of someone who longs to teach others to engage the texts of the New Testament with honesty and curiosity.
