Just tacking on to WFT's initial hype-killing. I saw it first hand, too. Out of my friends and I, only one was thrilled to see her, and he's always the one to like the strange choices xD
But, of the rest of us, myself included, we started to see the appeal in her by the next day, and started to really look forward to her. She isn't exactly my cup of tea, but she looks like she'll be a ton of fun to mess around with.
So, in short, she did cause an initial hype-kill, but it was so short that it may as well not have been there.
That's how I see it.
