Finally a sci-fi worth watching, hilarious at alot of scenes and sad in some, this is what I get just from the 1st episode, the alien-Chiwetal Ejiofor is sent to Earth to help his species on his planet, gets aid from at one time in her life a promising young brilliant scientist-Naomie Harris, and in starting to understand the help she is giving, she is also helping humans to keep from becoming extinct. Bill Nighy's character from what I piece together so far is someone who knows Chiwetal Ejiofor's alien, possibly from the Alien's world, I'm not quite sure on that character but it seems that Nighy's character is a slightly evil character who wants something back. It is a fresh and new series finally worth watching. Very excited to see where it goes.
