He's best when not dealing with extreme subjects or dealing with the banality of them. Light Sleeper is a much better movie than Auto Focus.
But he's still uner appreciated.
Want to see a great performance by Bruce Willis, check out In Country.
Have you seen 'An American Friend'(1977). directed by Wim Wenders, starring Bruno Ganz and Dennis Hopper (as Tom Ripley - yes, that Ripley). Robbie Mueller shot it with incredible art amd shading. For my money it is what small film should be, if a bit ambiguous in spots.
