It's funny, a few months back I was having a conversation with someone I knew about Falling Skies. He began asking "what's that other show, the one that's basically a rip-off of Falling Skies?" So I typed into Google "Falling Skies rip-off" and the very first result was about Defiance. Next time I saw my friend, I said "I typed 'Falling Skies rip-off' into Google and it came up with a show called Defiance." He responded "Yes, that's it. I knew it was called something that reminded me of Star Trek."
Okay, to be honest, Defiance doesn't sound anything like Falling Skies aside from being set on an alien occupied Earth. Defiances sounds interesting, and I'll be sure to check it out when it airs, but I thought the story was amusing all the same.
