Sarabi is awesome! ^^ Like many others have said, I wish she had more lines and more parts. Though I kept wondering when I was a little kid if she was voiced by a guy, because her voice sounded like a guy at the time.
What erked me though was that for all those years when Simba disappeared and Mufasa died, the lionesses couldn't see that Scar was as screwd as he was. It's like Disney was trying to pass Sarabi and Nala as smart and strong characters, but just not in reading Scar's actions. I guess it was mostly emotional truama on their part though. They were desperate for a king and didn't question why Scar would act the way he did.
But then again, they probably did, but it never was shown in the movie I guess.

Anyhow, on Sarabi, I love how she confronts Scar and says, "If you were half the king Mufasa was..." She had a REALLY great potienal of being a bad ass character. Just everything about Sarabi says, "Strong Lioness".
