What was the 90s Sci-fi show about savage aliens that “ate” human’s life force? There was a show with a groups of aliens that came to earth. It was a savage race that fed on the life force of humans. They “ate” humans by sticking their claws into the human's chest. There was one young human/savage hybrid boy. And he was trying to avoid eating human life forces like the others. But the desire to eat humans was powerful. I think they had dreadlock style hair. That’s about all I remember. I can’t find the name of that show but I want to watch it again. Please help if you know it.
