A sophisticated film, not for the casual watcher who just wants to be entertained.

Rating: Null/10 (18 March 2000)

There's no way around the fact that smack in the middle of this fine movie is a very bizarre, graphic "sex party", and that quite understandably will completely turn off a lot of viewers. However, it, or something very similar, is essential to telling the overall story of a couple's marital trials and ultimate strengthening of their bond. This is not a movie that you can casually watch for an evening of light enjoyment.
On the other hand, if you trust the director, and commit to watch the whole movie, overall it is a fine film with a rewarding story. I give it 8 of 10. It is telling that "men under 29" gave this movie its highest ratings and preponderance of "10s". Heck, when I was that age any movie with frontal nudity would get my "10" even if there were no story.
I viewed the DVD version. While it is sharp, beautiful, with good sound, there is nothing remarkable comparing this movie to others on DVD. The extras are limited, but include interviews of Kidman, Cruise, and Spielberg on the life of director Kubrick. Nothing else of interest.
April 2013 edit: Saw it again on DVD, I came away less impressed, it certainly isn't one of my favorite Kubrick movies.
