The first series of this immensely fun comedy introduced us to almost loveable 'Harry' - an alien with an unpronounceable real name (played brilliantly by Alan Tudyk) - who has been sent to Earth to wipe out humanity. 

Taking on the body of Dr Harry Vanderspeigle, a corrupt doctor involved with a crime syndicate, and learning about humanity by binge-watching Law & Order, he quickly finds that his task isn't as easy as his thought. 

The second series starts soon after the increasingly manic events of the first ended, and things get even more surreal - while the fourth and most recent series will also be the show's last. (Four series)
