She's incredibly strong, smart, has a sense of humor (something the original MK female didn't have), chooses to join the Special Forces on her own - going against what her father wanted for her (most of the other characters were all forced into the MK mess or did so for selfish reasons) and her gameplay is pretty f***ing great, imo.
The only issues I had with her in MKX was that her Fatalities were garbage and she was just a little too petite. Otherwise, she's one of the better new characters. She easily puts Kung Jin to shame. She's not so similar to her father that she feels repetitive (unlike Cassie who is just a mixture of Johnny Cage and Sonya). She's awesome. Simple as that.
She may not have an iconic ninja look or visually standout next to some of the other characters, but that doesn't make her "bland" or "worse than Mokap".
