A fascinating film for a modern classic in literature (that I have not read... though I have read Song of Solomon, and it's perfection). The film is strange, but deeply empathetic towards its characters and their strife, but it is Jonathan Demme, so what would you expect?
It's in some ways psychological horror, given that this is a film about a black woman in the aftermath of the Civil War being literally haunted by her past in the form of ghosts and walking corpses. But, truly, this is more of a drama about the deep scars that slavery has inflicted on this country, mostly, obviously, on the black community.
The performances are top notch, as is Tak Fujimoto's cinematography. This was a big box office bust in '98, but it's a film well worth catching up with.
