This movie is based on a very interesting story of an immigrant family and their transition from traditional Iranians to modern Americans. It is presented mostly through the eyes of a young writer, who is also the protagonist, and de facto heroine. Her life and her family's are really quite interesting and well deserve a movie to present them to others. The movie should be entertaining to those interested in the modern history of Iran, emigration to the US, and the changes within families after settling here. It's also a case study of how self involved parents can emotionally neglect their children. The acting of the mother character, both as an adult in the US and as a very young woman in Iran are strong points, and the actress acting the newly married young wife is excellent in her role.
Unfortunately, the first half of the movie is full of extraneous scenes that are more about the chaotic lives of 20 somethings than about the cultures. An example is an over-the-top female impersonator, with a British accent to boot. The overly rapid speech and unclear English diction in places were also handicaps. If you are somewhat bored during the first half, be patient, as the film gets better in the second half. Then, it starts to portray the heart of the family's story and their motivation for emigrating.
Overall, the tone looks like they took a fine story and dressed it up during filming with a lot of distractions, presumably to hold the attention of those viewers who need some fluff with their drama. By contrast, "The Quiet Girl" is also a film about a girl raised under trying circumstances, but it focuses on the story line, without much gloss. The Persian Version is like listening to a good story told by someone with ADD. You'll eventually get the story, but meanwhile you'll waste some time with their distractions.
I would have rated this higher, if the editing had focused on the heart of the story.
