Loved Alien Nation. Sykes and Cathy were supposed to have a big Rogers/Astaire dance number in one of the TV movies, but I don't think it ever happened. Sad.
And one episode had a gay human/newcomer couple, very cool.
I thought Gary Graham was hot, too. He disappeared for a few years and then reinvented himself as one of Hollywood's Persecuted Conservatives ("No one will hire me because of my views!"), a la Janine Turner.
He writes for Breitbart now.
