10 Best Performances In Buffy The Vampire Slayer
4. Alyson Hannigan - Willow Rosenberg
When Willow cries, we all cry, and that's a testament to the acting talent of Alyson Hannigan.
Willow Rosenberg went through a lot. Sure, she did some bad things too - like the entire magic addiction/Dark Willow thing in Season Six - but it doesn't matter whether she's being evil and killing people or being goofy and lovable, because Hannigan always kills it. Her growth from shy high schooler to loud and proud lesbian to Big Bad to most powerful Scooby is amazing to watch, and it's Hannigan's ability to hone in on the emotions of her character that make her so good to watch.
Her best performances can be seen in episodes such "Lover's Walk", "The Wish", "Wild at Heart" and every episode where she's all evil and vengeful. Her arc is impressive, even by Buffy standards, and thanks to Hannigan Willow never feels dry, or over the top or too silly. In fact, with Hannigan, you've not just got one of the best performances, you've got one of the best characters.
