Purely Disturbing film.
First, the making style was different. Scene after scene it runs switching past and present.
Second, storyline, casting, acting was okay. Definitely the bad guys make us think, 'hey, just let go of the family.'
Third, the disturbing end. It affects you only if you think about it after watching the film. It haunts for days. I can give you as warning.
This movie is not for soft-hearted. So skip it if you are.
