So glad to see that Defiance was renewed. I fell in love with the characters and the plot lines

Take it from me. This is science fiction not science fact. So the aliens can look like anything in the imagination of the show's creators.
Here is what matters: Do I like the characters that I am supposed to like and despise the characters that I am not supposed to like? (YES!) Are the episodes entertaining? (YES!) Will I watch the series when it returns (H*** YES!!!)
Thanks SYFY!

I think that Defiance is Fantastic. It is refreshing and like the some of the social ethnological parallels with Native American and S. Pacific Island Peoples. I am looking forward to the new approach in 2014!

I stopped watching the show the second they killed Gale Harold. Boring show.

As I understand it the aliens didn't know the earth had life on it when they set out from their corner of the galaxy. They tried for years to find a way for their people to share the earth with humans but one thing led to another and war broke out. The war came to a end when someone, not sure if it was alien or human, blew up the "Arks" that where in orbit causing a uncontrolled terraforming process on the surface of the earth. That should help any confusion

The plot doesn't even make any sense. These aliens did not come in peace. They invaded. Thats what immigrating somewhere you are not wanted means. And how can the Irathis be at one with nature, when their very presence on the planet is unnatural. They did not even bother to make it make any sense because its all about publicizing the game. If this show succeeds it will be a real blow for well written tv. Why bother with good writing when you can just tir a story into a first person shooter instead?

Bub... isn't it so strange that nature would produce something so similar, given all the aliens are governed by the same laws of physics? We know life exists on our world, so we know the prerequisites for biological evolution... bi-pedal creatures are the most advanced on Earth and, since we live in the same Verse - with the same physics - it stands to reason alien life would develop in a simlar manner to humans. The variations would come in the physical appearnace, not the physical composition...
Now, if they were from another universe, where totally different physical laws apply, then we could expect the evolution of something inconceivable, in comparison to our current paradigm...

Why? This is nothing more than a soap opera. There's almost no "sci-fi" aspect to the show other than the make up on some characters. Strange how ALL aliens breath the same air, are relatively the same size, have two arms, two legs, same basic physical structure. All Speak the same language. Yeah.. sure sounds like sci-fi doesn't it?

YES!!!!!!!!!!!!!!!
