As someone who's read the source material, is there enough there to keep doing these shows. I imagine if your writing something like a comic for something like this, it probably works out perfectly because you can jump from group of survivors to another group.
Like I could imagine this season progressing without ever revisiting the black guy and his son. Then next season jumping to them entirely. Or jumping to a completely seperate group in another part of the world all together.
And since it's already been picked up for a second season, then that I'm guessing means we're not gonna get a lot closure on this season in terms of what the cause of the outbreak was, what the solution is, or any long term resolution for this group of survivors.
