I began to dislike the show this season, every plot point seemed to just be random filler so far. They had the cannibals for a few episodes, then the hospital and we found out their back-story and what not just for them to die a few episodes later. The cure idea was the only thing that had my interest and that was quickly squashed.
These things actually made me stop watching the show for a couple of months because it just felt like they were just doing random things to keep the show going and make more money. When I compare it to Breaking Bad, Game of Thrones and House of Cards this show really doesn't rate highly with me anymore.
