Re: could they do a show with "realistic" aliens?
I loved the puppets on FarScape. The likes of Pilot and Rygel had far more development and depth than Mayweather or Kim. I'm on a mammoth rewatch of the series at the moment and I find that I forget/ignore the fact that they are puppets because they were done so well.
