The movie can be summed up in two words: Al Pacino.
Another brilliant movie by Al Pacino. Harassed and sleep-deprived, the LAPD detective sets about solving a murder in a far-off small town. Drifting between wakefulness, hallucination and nightmares of a crime he unknowingly commits, Al Pacino defines a cop's life in a new way. Rest of the cast supports well, although the movie is all about Al.
I like the advice he gives, in the end, to the rookie cop who is too enamoured by him and is drifting from the right path, to protect Al. He says - "Dont lose your way".
Sales and Finance are jobs where I've seen people lose their way. For short-term gains. "Dont lose your way" is good advice.
