Query: A very sad, but powerful movie

This movie is very sad and is too realistic. It is so real, it is scary. It has a very sad ending, and it is a movie I will not see again. It is not worth it. But don't get me wrong, the quality of this movie is superb. This movie is not really appropriate for the little ones, 8 and under, but that is my opinion.
