A problem she shares with Pym, is that Wanda doesn't have enough memorable big hero moments, to overshadow the big dramatic missteps. So the bad gets remembered, because there isn't enough big good stuff to remember. (Many of her heroic outings have been while partnered with Avengers like Captain America, Iron Man, Thor and / or the Vision, who were more likely to get the climactic 'oh yeah!' scene, barring that time she toasted Ultron after he clobbered half the team.)
