Few movies do honor to the books, and this one is no exception, it distorts the story to adapt it to something totally different, at times it is very dense, and tries to fill with images and music unintelligible things. The effects technology of the time doesn't help much. Essential parts of the story were changed and details of technicism that confuse or remain as a nonsense, missing dialogues and details, to maintain the plot and the suspense of the real dilemma posed by Asimov. Many of the scenes lost the essence of conveying the main idea, a yawn. I hope that someday they reverse it into something better.
