Maggie Smith: Everyone on Downton Abbey is excellent, don't get me wrong, but Smith owns every scene she's in.
Catherine Tate: Like many people, I had reservations about Donna Noble on Doctor Who. She was loud, abrasive, and came off as Bridget Jones on steroids. Her ensuing tenure became one of the most wonderful surprises I've ever encountered, as Tate brought out Donna's kindness, bravery, loyalty, and genuine humor, so much so that Donna's become one of my all time favorite Doctor Who companions. Sometimes I love being proven wrong, so thanks for that, Ms. Tate.
Peter Dinklage: It's become so cliche to love Dinklage and Tyrion Lannister, but, damn it all, he just inhabits this role so beautifully and fully, that how can I not love him?
Sarah Chalke: Like Catherine Tate, she brought out lovely nuances in a potentially obnoxious character like Elliot Reid. Well, at least until everyone on Scrubs became human cartoons, and even then Chalke couldn't do anything to redeem her, but still...
Elisabeth Moss: So glad this woman finally got some damn recognition at the Golden Globes, even if it wasn't for her masterful work on Mad Men. Moss has Peggy Olson's journey so compelling over the years.
Kelly MacDonald: I've seen MacDonald in movies before (Nanny McPhee, No Country for Old Men) became an overnight fan of MacDonald's after seeing her on Boardwalk Empire. What a talent!
