I did say, in my opinion. I liked the addition of Anita because it was nice to see someone affected by the actions of Killua and his family. It humanized it a bit for me, which is why I personally enjoyed the addition. As for emo Killua, I didn't really find him to be all that emo to begin with. Moody at times or down in the 1999 anime at times (like all of our main characters), but not completly "emo". Besides, seems that was dropped really fast, unless my memory is failing me, or either it was so underplayed that it didn't leave a big impression on me. He has issues trying to resist his natural instinct to kill. This is something that I wish the manga would've touched up on, because it was interesting to me and would've added even more depth to Killua's already, in my opinion, deep character, given his upbringing... I liked the idea of his trying to fight the urge to kill if he could help it.
I also found that more interesting than Netero's game...then again, I was never a big fan of Netero to begin with, so maybe it's bias on my part. :-P
