Yeah that was it's peak. I honestly would be surprised if the show goes into the next decade. It doesn't have the juice anymore and even the hardcore fans in the thread here seem tired of it.
I watched a few minutes of the first episode of Fear the Walking Dead and shut it off. Unneeded origin story of the same tired **** we've seen a thousand times.
I watched 28 Days later again recently and they give you the origin of the virus, but it's where it came from... not what the hell it is. I have respect for that, not everything needs to be answered.
