Interesting no one seemed to have watched this before.

First episode was a good introduction. 1st thing that came to mind watching this : Sky Captain and the World of Tomorrow. This show has the same retro-sci-fi feel to it. It's set in 2000 but the technology and designs are from the 40s to 70s. the aliens shoot weird oval beams like in old B-movies and they are, like all aliens, planning to take over the earth. And they start their attack Independance Day style (that's a pure re-enactment of the scene).

I have NO idea where the show will go from there, but... I'll stick with it.
