LOVE fallen Skies, and I had all the Deluxe box sets of Farscape..
It was the 20th Century bloke in the futuristic setting that was captivating, and Scorpious... Only downside... puppets!!
Heh don't forget the orignal 20th Century bloke in the future Buck Rogers!

And of course the only reason to bother watching it was Erin Gray in those Spandex outfits!
As for Farscape and puppets, tbh it was better than the dodgy cgi of aliens. It meant they could use their imagination and bring us some rather bizarre alien species. The fire spitting toad guys were great.
