Still remains the best. The absolute best.
A flawless, subversive noir and a deeply nihilistic work told through the lens of Vietnam-Watergate era America.
Walks a breathtaking tightrope of being almost too thematically on-the-nose ("one side is just losing slower than the other", "take a swing at me the way Sam Spade would") and almost too obtuse and distant without becoming either and, in fact, finding a perfect balance.
Also, Hackman's hair and mustache are gold.
