Alien invasion.
Aliens invading earth for resources when there are plenty of planets out there in the universe.
Independence day.
War of the world.
Cowboys and Aliens.
I never understood the genre of an advanced alien civilization that have FTL technology willingly coming to earth for resources.
Like why come to earth for resources when there are millions of dead planets out there which is mainly composed of one element.
Want gold, try Psyche 16.
Want diamonds, try 55 Cancri e.
Want water, try Kepler-138c.
If the invasion is about experimentation on human beings or harvesting them for their brains like in Beyond Skyline, then it's understandable since you can't find such resources anywhere else.
But for resources like molten core or water that can be found elsewhere then it's plain stupid.
