Babel - 5/10.
This is a movie trying to be more than it is.
It's billed as a complex story intertwining 4 different familes in different parts of the world, but, it's not. It's a story of crap luck involving mostly one family, somewhat less another family, and very peripherally a completely unrelated scenario in a third. Oh, and the nanny.
The complexity comes not from the story but from the story having been broken up into 3 parts which are then presented out of order, and occasionally interrupted by a tacked-on scenario involving a lonely, moderately hot japanese girl who gets naked.
