This action series tells about a group of adventures in the humanoid. These organisms resemble a lizard and are resistant to microorganisms. Over time, they try to regain control of the earth where things are collapsing because some humans work with them permanently.
Even at the risk of losing my street cred, this is a show that I enjoyed much more than I probably should have. With the right mind set, this is strangely addictive stuff and well worth a view.
The problem is that all originality in the concept was really spent with that first miniseries, and by the end of the second the characters and struggle became stale.
The story of Earth being invaded by friendly-looking "Visitors" who actually turn out to be man-eating reptile people was pure 1950s sci-fi claptrap... but unfolding over the course of a two-night miniseries, it was cheesy good fun.
On the surface it might be a series about giant spaceships and lizard-like alien overlords, but it doesn't take much digging to uncover a parable about the rise of fascism and the second world war.
