Haven't read the comic book it made a great impression, and my wife, who loves the book, also found the film worth seeing. In most ways its a sad story about life in Iran, before, when the Shah ruled, and after, when the Muslim clerics rule, but it is seen through the eyes of a mischievous young girl, who eventually goes abroad, when the repression gets too much even for her parents.
Iran was not a paradise under the Shah, and it is even less so now.
An important document, and a voice that refuses to shut up - well worth any penny you pay for it!
