Convoluted, cartoonish neo-noir
The neo-noir movement of the 70s, decided that a ridiculously intricate plot was a necessity. You need a guide book, to keep up with who is doing what to whom. The original noirs were basic.
The Southern caricatures are grating.
Griffith plays the same character from "Night Moves," basically.
I lived in New Orleans not long after this film was made, and the reality was ten times more interesting than this cinematic mish-mash.
