I haven't seen it yet, but I'm really interested in seeing it. From what I've heard, the writer/ director Peter Sohn, said that his grandma's dying words to him were, "marry Korean". He then falls in love with a non-Korean girl and struggles with how he can still honor his grandma. This becomes the inspiration for the movie. It seems like this is Pixar's take on trying to address immigration and interracial relationships. Again, I haven't seen it yet, so I'm not sure how successful they were, but I find the director himself interesting so I will give the movie a shot.
