Input: Jack's Best Work . I can't remember when I saw this one on the big screen.  It was not long after Easy Rider and we had the idea that this Jack Nicholson had something to say to our 60's-70's counter-culture.  He did have something to say with some of the sharpest acting I had ever seen. He out-classed the James Dean's and Marlon Brando's, but not with ease.  Jack was workin' hard, switching from depressed concert pianist to hillbilly good time dude to misunderstood Romeo in five-minute intervals.  No, make that changeable temperament every five seconds, truly an artistic milestone. Throw in an equally magnificent portrayal by Karen Black, sexy and hillbilly; Jessica Simpson, eat your heart out, and you have the couple of the year, 1970.    Jack's father is one of those evil patriarch's that hurt their kids bad, pushing them to greatness without an ounce of love.  Consequently, the siblings are brilliant and eccentric.  The daughter is a frumpy dope.  The older son is a violinist with a neck injury, and then there's handsome Jack, shiftless, moving from bed to bed, crossing the country, a boozing bum.  Back in the Vietnam years there was an examination of bourgeois life.  Did we have to get a job and get married?  Was everyone in a particular cubbyhole, mail in the funeral?  Hence, we had the counter-culture, drugs, long haired hippies, sexual openness, and shiftless lifestyles. Bob Rafelson's film gives you that, but mercifully, with subtly.  That last scene at the gas station says it all.  I think directors would be hard pressed to sum up a film's theme so effectively with so little noise - amazing.
Output:
POS
