Thoroughly enjoyed this movie. Aliens travel from one world to Earth. They are subjecting humans and use them as hosts. Naturally, humans are outmatched but rebel as they learn to resist the alien invasion. In this story, the aliens have depth other than just domination. Some aliens are sympathetic to humans. Brought on by occupying the thoughts of humans and sharing their existence and thoughts. Others (aliens) are all about the process. This story tells a story of the occupation of this alien race
