With the recent release of The Day The Earth Stood Still, I found 10 movies where aliens think we are just puny humans and not worth it. They think they can do what they want with us or Earth is their private battleground to battle other aliens.

Let's start with the older movies

This Island Earth (1955)

Aliens come to Earth seeking scientists to help them in their war. But what is behind their motive?

The 27th Day (1957)

Five individuals from five nations, including the "Superpowers," USA, USSR, and China, suddenly find themselves on an alien spacecraft...

The Hidden (1987)

An alien is on the run in America. To get his kicks, it kills anything that gets in its way, and uses the body as a new hiding place...

They Live (1988)

A construction worker find sunglasses that show the real faces of the alien invaders.

Abraxas, Guardian of the Universe (1991)

An alien "policeman" (Abraxas) arrives on Earth to apprehend a renegade of his own race who impregnates a woman with a potentially-destructive mutant embryo.

Independence Day (1996)

The aliens are coming and their goal is to invade and destroy. Fighting superior technology, Man's best weapon is the will to survive.

Battlefield Earth (2000)

After enslavement & near extermination by an alien race in the year 3000, humanity begins to fight back.

Alien vs. Predator (2004)

During an archaeological expedition on Bouvetøya Island in the Antarctic ocean, a team of archaeologists and other scientists find themselves caught up in a battle between the two legends. Soon, the team realise that only one species can win..

The War of the Worlds (2005)

As Earth is invaded by alien tripod fighting machines, one family fights for survival.

Transformers (2007)

An ancient struggle re-erupts on Earth between two extraterrestrial clans, the heroic Autobots and the evil Decepticons, with a clue to the ultimate power held by a young teenager.

If you noticed, some of those movies had sequels(The Hidden) or being redone again(They Live). Yes, aliens think we are just puny humans but they do find that we can fight back sooner or later. ;)
