Werner Herzog is a sick freak.
But I mean that in a good way. I've only seen two other films of his, "Grizzly Man" and "Encounters at the End of the World", which were documentaries. After viewing the fictitious "Bad Lieutenant: Port of Call New Orleans" my suspicions of his wicked sense of humor are confirmed.
This film is similar to the original 1992 "Bad Lieutenant" (directed by Abel Ferrara, starring Harvey Keitel) in that it profiles a totally corrupt, drug abusing police lieutenant. However, while the original "Bad Lieutenant" contained no comedy and sends Keitel progressively downward from bad to worse to things can't get any worse than this... Herzog's "Bad Lieutenant" is full of a variety of comic styles from dark humor to absurd humor to plain old silliness. (In one scene, Nicolas Cage (the bad lieutenant) asks "what are these iguanas doing on my coffee table?" and the scene suddenly switches to the point of view of an iguana. The scene is almost entirely silly and pointless. I'm out of room now.
