A wasted chance

I so agree with you!!!
I had just learned that it wasn't filmed in Iran which takes this whole movie into a whole other strange hybrid of Western colonial pop art mashup. Even though the director is painfully enamored with North America and the west, she still could've bridged some new insight into, say, European / Iranian identity.
What we get is a young ladys' rendition of:
1. James Dean via rebel w/out a cause..
2. David Lynch (for a dose of experimental and "INDIE CRED")
3. F.W. Murnau - nosferatu
4. indirect john hughes movies
5. and of course tarantino and American pulp
6. et. al......
put into a blender with black and white photography.
"A Girl Walks Home ...." is simply San Fernando Valley teenage vampire flick dressed up in a burka.

There definitely are true Iranian film directors via Abbas Kiarostami. And @gargarie you are so right that this film merely elevates the worldview its audience wants desperately to see represented.

And at the end of the day this all doesn't mean much if it wasn't for the fact that Iran has much to add and say as anyone to world cinema and that this Eurocentrism in hollywood that this director blindly has been brainwashed into is at its all time high.

Great questions Bagrawr:
My response to your 2 points:

1) First,
Many of the great foreign directors definitely DO NOT work for the pleasure of Westerners nor have them in mind. And because of this, whether they try to or not, out of their work they've created an awareness for outsiders (Westerns per example) about the bigger world out there. Because of this their work gives us a bigger perspective of the world and takes our minds off of a certain Western colonial mindset i.e. Western measurements of beauty and Western measurements of moral agency (to name a few). And so yes, because of this, they've given us cultural insight.

Example, director Niri Bilge Ceylan:: Are you familiar with him? He's Turkish. He has made it plain and clear several times that he's not interested in journeying to Hollywood nor in making some Western film to appeal to Eurocentric, culturally impotent tastes.

This director, Anna Amirpour so far, is completely unoriginal. Just a "regurgitator" of Western pop culture pastiche.
But of course, there's a high chance that if someone - such as herself, syncs "cool images" in the right way with hip, "indie" music and then throws in something a little surreal (to seem artistic) you may have a audience hit.
Which she's done.

2) Second:
She's from the West and not a foreigner (from the East) Some interviews has revealed she's lived a privilege life across the pond in Great Britain.
The major problem with this mess of a film, other than it's hipster unoriginality, is that it was publicized by her marketing team as an Iranian vampire spaghetti western.
Theres a vampire in it. There's American cowboy nonsense in it. There's a burka in it. Yet, this isn't Iranian at all!
