I find this movie very enjoyable. Character interactions, emotions, scenes, dialogues and so on. The only problem with it is that it doesn't belong in this world. There are no people like this. I've spent most my childhood surrounded by right wing skins (many of them still my best friends). Then I've spent nearly 10 years being an immigrant and surrounded by people of very mixed origins. Again I repeat - people are not like that. What this movie does is it perpetuates harmful stereotypes and prejudice on both sides in the name of universal love and leftie brainwash. Use with caution.
The director is very talented but should rely more on his own life experience when telling stories rather than doing his liberal homework to get praise from his Starbucks friends. I think it would take him to another level.
