Haters? Where? *loads shotgun*
right here.... kind of.... I just didnt like the idea that Anakin had an apprentice since you would think something like that would have come up in the movies. It felt like pandering just trying to get in a new demographic rather then an actual good story choice...... and for the start thats exactly what it was.
heck you didnt even need to make her Anakins or Obi-wan's padawan she could have just been one of yoda's that didnt have a master and was just traveling from master to master or something and it could have worked.
So dont hate her, just the concept of her.
