I thought the first two were great (although I'm not sure if I remember much hilarity) but the third didn't need to be written and was more interested in political commentary than plot.
I'd say stuff like Savages and Death and Life of Bobby Z were a bit lighter with more humour.
Winslow's Power of The Dog trilogy is a dark dirty thriller about drug cartels and cops on the Mexican border.
Compelling memorable and at times darkly hilarious
