After whatching this one, i decide that i will follow the diet of celestial Mana. So, the theme is essencially the pursue of the need to be sure of the truth. This is also a film about how our parents are full of shit, and we when young and inexperienced in life, feel ourselves under the obligation to give them the hope they need, even if we die from silent, or exhaustion. Some parents can be wretched, evil, bastards.
