In particular he makes reference to the excellent NT theologian NT Wright and some of the deeply challenging things he has written that force us back to the gospels to find the Jesus we've often missed. Often Wright has 'spoiled' our commonly held ideas of Jesus - but he has replaced them with far deeper, more truthful and powerful themes from the scriptures.
Liethart makes the following observation:
Several years ago, when The Passion of the Christ was making headlines, I realized that N. T. Wright has spoiled every Jesus film. Once you’ve read Wright, you realize that none of the movies get Jesus right. Pharisees and scribes are reduced stock villains with caricatured Jewish features. Pilate has to make an appearance, and Herod, but we are given no sense that first-century Israel was the powder keg that it actually was.
No film ever gives us what Wright says we should be looking for: a “crucifiable” Jesus, a Jesus who does something so provocative to make the Jews murderously hostile. In the movies, Jesus is a hippy peace-child, a delicate flower of a man, a dew-eyed first-century Jewish Gandhi. Why would anyone want to hurt Him? Maybe because He’s so annoyingly precious; but that’s not the story of the gospels.
