I think from the beginning one of the main appeals of SW has been the intriguing side characters. Everyone has their favorite characters that have one line or less. And the franchise has done a great job making diverse cool looking backgrounders.
I agree with this. And I've grown to like Aurra due to her appearances in The Clone Wars and in some other side stories.
This may not be exactly where @LordZeppelin is coming from, but my issue with her was always the feeling that they tried to make her a thing. Like, they had her for a split second in the podrace to draw attention to her. Instead of the cool and intriguing side characters from earlier movies, this felt like a flag being planted to be used later. And my memory of things was that some fans immediately took the bait and got super-obsessed with her...with at least part of it getting turn-of-the-century internet creepy. Maybe my memory is off, as I don't remember seeing that so much as I remember seeing people talking about seeing it. But I do recall hearing that it got to the point where Lucas said "ehh, maybe let's not bring her back to the movies," and we got Zam Wesell at the start of AOTC instead of Sing.
Between the try-hard introduction and the chatter about her afterwards, I soured on her. Like I said, I've grown to like her over time. She's a cool alien and a cool bounty hunter, and I'm excited to have her somewhere in my scum display.
