I think that "Palmetto" is going to be a cult movie some years from now. It has been clearly underrated. It is "noir", although located in sunny places. It has a sort of kinship relation with George Stevens' A Place in the Sun. And it has a quite good Woody Harrelson in the leading role. Sweat plays more than a role in the plot: characters are sweating all the time (mainly Harry Barber), for different reasons. May be that's why some people dislike it.
