Real stories have change. The hero gets his ass kicked in the beginning but by the end he kicks the villain’s ass. The world is saved. They get their lover. The hero is redeemed for his past transgressions. If none of this happens at least leave a little smidgen of hope in your ending. A sequel can be fun too. That is reality, without the sequels.
Sure, there are people who take advantage; there are always people who will do things like that. But in the long run you’ll see images or videos of the young helping the old. Or you’ll see neighbor helping neighbor. I end Wish List with the Wendigo resurrecting. But it’s not a global meltdown. It just ends up bad for Josh. Josh was screwed from the beginning. He deserved to die. There are consequences to murdering people.
This whole concept of letting death happen when it can be prevented is ridiculous. If the situation in the story calls for death all around, then okay, go for it. The Grey ends like this; it’s an overall good movie I guess- except for the wolves’ behavior... With everything that the characters had gone through, and they’re low resources, they couldn’t possibly have survived. Valhalla Rising is the same way. The Native Americans absolutely slaughtered the Vikings in that movie. They didn’t want new gods or new intruders. The Vikings were severely outnumbered.
