Anyway, I think that trailer pretty much turned around my opinions on the show.
I mean, for the first Season, anyway.
After one Season, then it'll pretty much stop being unique.
But, we really have never seen everything breaking down right at the start of the Turn in the TWD Franchise, and it looks like that's basically what FTWD is trying to do. And while I wasn't excited for it before, seeing just some footage of what they're doing... yeah, I am now.
But seriously, after one season, I'm not sure what they can do with this. Then it's just TWD: LA. Which, means it will have a very different aesthetic and feel to TWD, and will tell a new story, but it will probably lose something. I mean, it definitely will lose something. Although, maybe they can come up with something else, I don't know.
It's already been confirmed for a second season, and even if i'm not kind of optimistic about this season, I'm dreading the second. Once you've shown the story of L.A.'s fall, then it really is just another Walking Dead story.
Although, allow me to speculate, these people don't really look like survivor material. My guess is that they want each season to do something the main series hasn't done or can't do. So...
Season One = collapse of a major city/beginning of The Turn. Something unique that gives the show a new feel, I think they can pull it off and separate it form the main series.
Season Two = learning more about the virus, but given that Kirkman doesn't really want to do that, I'd say it's unlikely. Another possibility is that they'll become part of a large group run by someone like The Governor or Carver, essentially the same story of the TWD Novels Road to Woodbury and The Fall of The Governor. Could be interesting... I guess we'll see how it goes.
