Action Scene at Beginning (Spoilers)
The opening minutes of the movie show the good, simple life of Tre Crusus, New Mexico...
Followed immediately by one of the most violent bank robbery scenes I can think of up to 1971. Five people shot in 30 seconds, four of whom die. Very well staged scene which shows the results of a crime like this.
This is one of the few crime dramas where you root for the bad guy, who had a hand in the death of two law enforcement officers.
