Just how accurate is Tina Fey‘s impersonation of Sarah Palin?

"Dead on," says Palin’s sister Heather Bruce.

Bruce told The Insider in a two-part interview airing Thursday and today that "Tina does a great job. Maybe [she] goes a little bit overboard with the sarcastic expressions, but I know that’s Hollywood."

Bruce couldn’t make herself watch Katie Couric grilling her sis, but thought Sarah would do a great job debating Joe Biden.

"I have a feeling people will see some of the old Sarah we know and some new great surprises and great revelations."

Turns out she was right.

Most critics felt that while Palin failed to be specific (again), she held her own against Biden in her inimitable folksy way, appealing to "soccer moms" and "Joe six-pack" sitting around "the kitchen table" during last night’s debate.

What did you think? Were you impressed by Sarah’s performance?
