The Japanese segment was interesting in its earlier stages. I was very sympathetic towards the deaf girl, but I naturally assumed that it would all tie in cleverly at the end. It never did.
The Mexican wedding bit was pretty good, until the ridiculous car chase at the end. That was almost as if it was thrown in there for no reason. It felt very out of place, and seemed like trouble created for the sake of it.
The Moroccan bit, which was the main bit had many interesting moments, though it didn't make sense to me why tourists would choose to visit the middle of goddamn nowhere. They were out in the desert where there is nothing to see, and hours away from any civilization.
Also the Moroccan brother and sister behaved in a sexually repressed manner that was definitely weird. The fact that they were sexually repressed with desires to explore reflected the thinking of someone with a Western upbringing. It was almost as if the writer thought,"Oh well they are young, without any contact from others so they must be undersexed and willing to go to weird lengths."
Yes children reach sexual realization faster in today's soceity, but that's partially because of the diet, and mainly because of the culture that has been developed. It is impossible for a child to grow up in today's world without being very aware of the opposite sex. I mean it is everywhere in the media as well as social settings. Kids can't escape it, and thus grow up faster.
However in the middle of a desert with kids no older than twelve, I found it impossible to believe that two siblings would be so sexually depressed that they would desire each other. That's total nonsense.
Some of the dialog that was written for the Arabs was very out of place, and felt unnatural.
I love how when the younger brother was confronted by his older brother about his sexual feelings for his sister he said,"This is between me and her, you stay out of it."
That was rubbish and got a good laugh out of me. It totally felt like a Hollywood line, and not like a nomad family. And where would a twelve year old boy even learn how to masturbate...
I am assuming the Mexican segments were better and more accurately written, because both the writer and director seem to be Hispanic.
