I have to say, I don't really understand the Rocket hate.
I admit she's kind of left field, but she's not an outright new character. But her personality isn't abrasive, and she hasn't done anything outwardly annoying, beyond being a bit enthusiastic.
Given her powers aren't that different than a Lantern, if they had gone with Arisia, Iolande, or Natu, but had her act basically the same (Happy, enthusiastic, a bit inexperienced, but with the ability to get serious when she needs to), would everyone still hate her as badly?
Using left field characters in unique ways is a staple of the show. So her addition really isn't surprising, when you look at Aqualad, Zatanna, and especially Artimus.

I just don't see how she's had time to do anything worth hating her over, aside from simply existing. 'cause like I said, she's not abrasive (Like Spiderman and Nova are), and she's not terribly boring either (Like Powerman, Ironfist, and White Tiger). For now, she's just... there.
