The dynamic of Jackson Healy and Holland March in The Nice Guys

Analyse the dynamic between Russell Crowe's character and Ryan Gosling's character in the new movie, The Nice Guys. I find that this dynamic is a new take on noire films. Perhaps a new era of this genre that involves two unlikely characters that find themselves in a particular situation; considered to each as the "big dirty." For once, it doesn't seem to involve the cops. . . and has sense of humor.
