She is such an extraordinary singer, who cares about anything else!!!! That final scene is one of the best moments in all of show biz - bar none!! I'm glad she kept the camera on herself for ten minutes - she deserves that iconic status - such is the power of the voice.
I first saw this film when I was five and it had a huge impact on me. I see it today, and yes, I can see some of the flaws (like Esther wanting to leave the Grammy's right as her award is being announced).
But some of the other user comments are just plain false - I mean, where is the gratuitous nudity - maybe we saw different films???
Streisand's singing ability is monumental, and if she has a big ego - fine!
She's earned it.
