Since we all think the plot will be stuff lets all develop a plot we can enjoy!
One day deep in the night, a large group of creepers come and attack the village. The creepers are killed and the explosion destroys the town! The people inside need to go deep off to find the necessary ores to rebuild the village. They cant gather any from nearby since they have already used all of them up. (underlying themes about don't over use natural resources and earth day)
A group heads out through the wild to get to a good mining spot. When they notice there are no monsters. After retrieving the ores they spot their first one heading deep into the woods. Deciding to follow it and see why they are all missing a portal is found to the nether world.
The group comes across a big castle in the nether world and sneaks in. Up from the roof looking down on the courtyard they over hear a plot to kill all the humans for destroying the caves in which they all lived! The group runs away and gathers everyone playing mine craft to go throw the portal and fight the army.
There is a big battle and everyone dies. The few remaining decide fighting is bad, wrong, a no no. Than the humans run off to a far away land to settle and leave the monsters in peace. They do not disturb any of the monsters there and use the only needed amount of resources being nice to the monsters and the earth. Giving everyone in the audience the general messages about recycling.
After the credits it shows one person in a boat coming to the shore of the old lands. Followed by a few monsters approaching and one blacks out the screen to help elude to the sequel, threequel, and fourth film. Followed by a tv series on nick or cartoon network.
