movie with the giant blue men circa 2000’s

In the 22nd century, a paraplegic Marine is dispatched to the moon Pandora on a unique mission, but becomes torn between following orders and protecting an alien civilization.

Set more than a decade after the events of the first film, learn the story of the Sully family (Jake, Neytiri, and their kids), the trouble that follows them, the lengths they go to keep each other safe, the battles they fight to stay alive, and the tragedies they endure.

A couple watch a 1950s B movie which seems awfully alien to them.

Two highschool students are faced with a threat like no other, a body stealing alien invasion stemming from some mysterious blue goo.
