The story lacks some details

Rating: 8/10 (1 December 2008)

The synopsis describes well the action of the characters in the film. So, I don't need tot turn back on this point. My point is that I think that the story lacks some details on two points:
1. I consider that at the end of the story, when the characters are back in United States, they aren't back to the "starting point" as some people wrote. That is, back to the state in which they were before traveling to Barcelona.
They aren't back to the state in which they were before traveling to Barcelona, because something new happened in their lives. This doesn't mean that their lives changed, but that their way of looking at life must have changed. This new way of looking to life should have been pointed out by the author.
I can't believe that the author consider nothing: (i) having an intense affair with a foreigner, while being engaged to marry someone (Vicky) (ii) having an intense affair in a threesome scheme with a very intense couple (Cristina)
2. I consider that the relationship between the three characters in the threesome scheme, should have been explored a bit more to help me understand better what was going on between Cristina, Maria Helena and Juan Antonio. The way this relationship was actually described makes me think that this threesome scheme was just a fantasy in the author's head. And, I'm interested in something more than a mere fantasy. Actually, my real life experience goes farther than the story in question.
The film is very good and I liked to watch it. My comments are only due to the fact that I would have liked to learn more about the characters mind.
