For fans who can't seem to get enough of The Walking Dead's universe, Netflix has a very big treat in store as two of the three spin-offs from the franchise will be available to stream in January in a bid to get rid of those winter blues. Based on the comic book series by Robert Kirkman, who also penned Invincible, Marvel Zombies and many others, The Walking Dead was a huge hit for AMC when it premiered in 2010. Amassing a loyal and dedicated fanbase in its wake, the post-apocalyptic show drew in more than 17 million viewers at its height, making it the biggest series debut AMC had seen to that point.
