Buffy
I know this sounds crazy, I'm a huge fan of Buffy the Vampire Slayer and love all the originals.
But watching Sarah, I feel like she could totally be the new Buffy for this generation. The comedic timing, the depth (watch XO she does great), she's stunt trained (Vampire Academy).
I just can't get it out of my head that she'd play such a great reboot of Buffy.
