I can't help but wonder why in all movies I've seen, from what I can recall, ghosts, spirits, apparitions and whatnot are almost exclussively evil, malevolent or harmfull. And I ask myself: why? I mean they can't ALL be bad. Infact, why would they be bad? They're spirits of the diseased. What motivates them to go around being dicks to everyone? Most of the time, the reasons are rather petty and shortsighted.
Are there any movies out there were the dead aren't vengeful?
