I must admit the two preliminary mini-series were superior to the attempt at an ongoing weekly show. Jane Badler as Diana. Marc Singer as Mike Donovan. Faye Grant as Juliet Parish. Robert Englund as Willie. Michael Ironsides as Ham Tyler. There was so much potential here. I think what sucked the soul out of the ongoing weekly show was the loss of producer/writer Kenneth Johnson.
I watched the movies and started to watch the series but the Alien invaders must have ercased my memory because I can't for the life of me remember anything except the premise of alien invaders and the big ships, and how they looked like humans but were really lizards and how they had infiltrated the world.
