Given the popularity of The Walking Dead, it's no wonder that the hit AMC series has so many spinoffs. While the spinoff about Michonne and Rick Grimes has gotten plenty of attention, Fear the Walking Dead is likely the spinoff that people are the most familiar with. The first episode premiered in August 2015 and the final episode aired in November 2023. But many might not know that there is also a prequel series called Fear the Walking Dead: Dead in the Water that is about the USS Pennsylvania.
