It is too bad this rates only a 5.8 by IMDB users. There is more to this film than the rather low rating. Check out the reviews on this page.
There are some great thought-provoking lines, especially by the Zen Buddhist monk, but also the dialogue between the two men and what happens to their marriages and families. Anyone caught up in the stress of today's modern world (and that is nearly all of us, right?) should watch this movie.
In particular, I recommend that all men watch this. It would be a good film for a men's group or those interested in psychotherapy. You women as well, especially married-career-family women: grab your man and watch and discuss it.
The biggest flaw was that I doubted if two men would REALLY do what they did on that island, with the young blonde and the construction. Too fanciful for me. But the messages in the film WERE reality-based.
The manner that sex was handled was done maturely. It is rated R18 down here in New Zealand, but the sex scenes are mild and not at all pornographic, and the resulting-final ethics are admirable and understandable.
It was refreshing to see a film with unknown actors, that is - without box office mega-stars.
By the way, my wife was half asleep in bed, ill with the 'flu, while I watched this. At first she mumbled that it was a silly B-grade movie, but as it went on she realized that it was actually a worthwhile film with depth.
