It’s a wispy movie that does not end so much as peter out, and it could have benefited from a little more humor and a little less heinous male behavior. Miller and Farahani, though — both sometimes used previously as decoration — give strong performances as women bonding over their delight in both movement and their own beauty.

This well-intentioned buddy-road-trip flick lacks the danger, the drama and the sex appeal that most moviegoers will be looking for.

What might have proven an illuminating perspective on familiar issues disappoints as Bouchareb fails to turn his outsider’s point of view into new insights, and instead takes the easy route, falling back on familiar stereotypes in his tour of US misogyny and xenophobia.

Miller, who's still trying to find her way as an actress, isn't bad, and the Iranian-born Farahani is convincing, but their characters are blandly angelic, in stark contrast to the vast majority of men they encounter.

Although fronted by solid performances from Sienna Miller and Iranian actress Golshifteh Farahani as two desperate souls who bond over their shared love of belly dancing, this tale of friendship and rebellion on the open road reps a thin, obvious reworking of a well-worn template.
