This movie is a comedy about three wives who eventually experience a very important shift in their lives. First of all, it is a very finely photographed advertisement for Argentina. There are a lot of common places, too many even for a light comedy like this: tango, Argentinian machos, horses, gauchos, cows, endless roads in the pampa. It is just the stuff that refined Italian tourists love.
It is also a kind of mix of previous movies, surely better than this one. For example it is really similar to "Thelma & Louise" (women on the road, a cop following, they are in trouble with their husbands, etc.). (Scott's movie is even explicitly referenced when we see the solitary bicycle rider, which in turn is also a hint to Lorenzo Jovanotti's book about his long bicycle trip through Patagonia... looking for his inner soul on Chatwin's track... more stuff to feed Italian new-agers).
It also looks very closely to "Caballos Salvajes", another road movie starting in Buenos Aires and ending in Patagonia, in which two men and a woman (really similar to the character here played by Spanish actress Silke) experience a radical change in their lives. In spite of the silly clichés, I admit that I occasionally laughed soundly while watching the movie and left the theater quite satisfied. I give this a 6 out of 10. I think that Italian cinema industry needs movies like this in order to resurrect completely to its splendor of old. Only, they should not be too ambitious, and "Tre Mogli" is.
A final remark... why is dubbing so poor in this movie (as in many Italian ones)? Silke is probably a good actress, but was it really necessary to hire her and have her blabbering randomly so that later the dubber (Sabrina Impacciatore) had to make an impossible effort to make acting credible? Moreover, few Argentinian characters are really played by Argentinian actors. Many are Spanish and occasionally they do a good job at modifying their accent (Loles León in particular), but some do not, not to mention Italian actors disastrously trying to fake!
