Why not?

I have an idea for a sci-fi movie:

Finally the question “Are we alone in the universe?” is answered: alien spaceships land on Earth. It turns out that aliens have no intention of invading our planet. On the contrary, they want to have nothing to do with us, humans, or our planet. The sole purpose of their visit is to dump their cargo - thousands of their fellow aliens convicted in crimes on their own planet. The Earth would serve as a prison for them.

After the initial panic humans find out that their new companions are not criminals, murderers etc scumbags but scientists and artists whose ideas are considered dangerous and threatening to disrupt the artificial order on their native planet.

The humans, who are on the verge of extinction, make the surprisingly smart choice to work together with the abandoned aliens and to restore life on Earth.

And they all lived happily ever after.

The end.

Life imitating art.
