American Horror Story, through all of its ups and downs, has remained a hotbed of acting talent since day one. Every performer gives their all each season to bring the wild and horrific imaginations of Ryan Murphy and Brad Fulchuk to life. There are clear standouts in the regular cast including Evan Peters, Jessica Lange, and Sarah Paulson. One of the more underrated performers, though, has been a series regular from the beginning and remains one of the show's most valuable players: Lily Rabe.
