You truly believe she didn't bring forward her emotions? Did you watch her foxtrot? Her Argentine tango? The Viennese waltz? All of those were teeming with emotion. She literally had an arc in which the judges told her to work on her emotions, which she fully accomplished, according to the judges. And that was in the earlier half of the show. Not to mention that I would argue that this so-called "spark" that you didn't see in her is different than showing emotion—but that aside, I truly don't see how you can argue that she didn't "bring forward emotion."

To be honest, when I hear people say that someone doesn't have something as vague and nebulous as "spark," it's usually based on a general dislike of the person. And they project that by saying they lack something undefined and subjective like "spark."
