That good can triumph over evil, that I can still dream the better dream, imagine the ideal, and watch it on screen.
Everyday in my life my idealistic tendencies die a little, realism surrounds me, good does not triumph, things do not change, the fight is meaningless.
Films like avatar, or the fantasy books I love so dearly, awaken that side of me again. Sure, I will wake up to all my problems and that idealism will slowly begin to die again, but for the time being it's sustaining me.
Nourishment vs the poison of day to day humdrum living.
