John Sayles repeats himself in "Silver City," borrowing very heavy-handedly from his much more effective takes on local politics and the environment that spawns it, from his "City of Hope" (urban NJ), "Lone Star" (Texas)--which also featured Kris Kristofferson in a not dissimilar role-- and "Sunshine State" (Florida), though now he's taking on Colorado.
Other actors also seem to be present for their resonance from other features, Michael Murphy from "Tanner 88," Daryl Hannah almost as crazy as she was in "Kill Bill, Volume 2," and Richard Dreyfuss channeling Duddy Kravitz as a campaign manager.
While Chris Cooper is very effective in capturing a George W. Bush-type politician from a family dynasty, Danny Huston switches confusingly from cynical ex-journalist/investigator to naif as he uncovers a scandal with ever-widening yet encircling entanglements of class, ethnicity, media, real estate, wildlife, etc. etc.
While the satire is scarily amusing, the final scene of this overlong film is literally overkill.
Sayles as usual carefully picks the songs on the soundtrack, here there's frequent Cowboy Junkies tracks.
