This show is so under-rated, and I'm glad other people here know how to speak through their mouths, as they have praised it (they deserve a wonderful life, full of blessings). I'm not generally a Gerry Anderson fan (the only other show of the genre that I love is Starfleet, the Japanese puppet series from the same era as Terrahawks). Getting Terrahawks back in my life is one of the best things that has happened to me this century. I love the music, the zeroids, Yung-Star (I would marry him if I wasn't so reluctant to have the most ghastly mother-in-law possible!), and Mary. My favourite Kate Kestrel songs are Responsible, and Be My Star Tonight.
I ask you, what other programme has robots as adorable as the zeroids? Not Stink-ray or Chunderbirds, for sure. I'm definitely a hawk-brain, not a bird-brain!
