Thee origins ending has received so much hate its ridiculous. Everyone thinks treyarch got lazy and ruined the story. Treyarch didn't ruin anything, they actually made the story more concrete. Zombies has always been a child's imagination, look at the clues right in front of our faces:
- Comic book loading screen
- Mystery box (aka toy box) that gives a ray gun (aka toy gun) or a teddy bear
- Sams room in kino has a model of der riese and a drawing of a map on her floor
- Chalk drawings give guns. The origins video shows this being like a kid drawing with crayons on the wall.
- Zombie outbreaks during different time periods and in very strange places, like why does the moon have a pyramid and a teleporter in the 60's?
- The demonic announcer is just the kid playing with the dolls
In the end the Origins video is the perfect ending to a game and a great cliffhanger for the next zombies game. Sam even tells us that Eddie will have control for the next map.
