How original...
Can you please tell me how many times we have seen this thing in movies? A patriarch dies, his estranged sons and daughters come to his funeral, and are unwillingly forced to stay together for a few days (Why? Can't they just leave after the funeral?), and they fight, and fight, and fight, and at the end, they realize how much they love each other?
I haven't seen the movie, but it's like I've already seen it five times.
