Saw the iTunes free download and kind of liked it. I think that the premise is intriguing but the dialogue was stiff and the character development was too abstracted.
I can agree the dialogue was stiff. For a while there I was having trouble understanding the "English" from the primary characters, but the character development within the framework of the story was acceptable to me. It deserves more viewing before I'll know if it is a keeper.

I have watched a lot of good shows on my Roku, like:
Sons of Anarchy
The Killing
Homeland
The Shield
NYPD Blue
The Wire
Walking Dead
I have indulged in the bolded titles.
