As another reviewer already stated, there are certain universal truths that ring true to everyone, no matter where you are from or how you lived. Well for most that is - because family and the relationships therein are always complicated. There is always love of course (at least a little bit of that), but there is also a lot of regret ... how and where you go when one of the pieces go missing (expires/dies, however you want to put it).
It may confuse a little bit, but the drama is worth it. This is for everyone who likes things to be "real life" and feel as real as possible. Secrets get revealed, passions exposed and other things that were under the surface. Now while that might sound exciting and powerful - it is, but not in a strong fast way, but rather a slow paced burning ... if you can dig that, you'll love the movie. If not ... well it's obvious isn't it.
