Great cast in an absurdist, blasé screenplay that clashes the reality of Brasil's social problems with the reality of westerners' views on it. A lot more subtle than, say, anything from Sacha Baron Cohen. A lot less hilarious, too. But its subtlety is not without some virtue.
Disparate foreigners seek sexual fulfillment and social justice in Rio, weaving in and out of each other's lives. Bites off a bit more than it can chew as its uneven structure becomes a bit aimless. Overlong by about 30 mins. The film would have benefited from trimming the fat a bit. Still, strikes nice tonal balance between comedy and seriousness.
