I didn't watch the interview. But I've watched the clips and it looks like Palin was Palin and Gibson was Gibson. I think this quote from NY Times writer, Alessandra Stanley, captures how it went pretty well,
"At times, her eyes looked uncertain and her voice hesitated, and she looked like a student trying to bend prepared answers to fit unexpected questions.
Mr. Gibson, who sat back in his chair, impatiently wriggling his foot, had the skeptical, annoyed tone of a university president who agrees to interview the daughter of a trustee but doesn’t believe she merits admission."
Here's a clip that seems have stirred up both sides.
Video of what Palin actually said and some analysis is here.
The Anchoress provides some thoughtful analysis and a lot of great links.
All in all those that like Palin, found something more to like. Those that don't found more not to like. The interview didn't accomplish anything, except maybe make more people - on the left and right - dislike the media even more.
