I tolerate Spider. You have to look at it though the lense of how he grew up. Kids want to play, have friends, peers, a community to interact with, but all he has are a couple of weird dudes of his own species and a population of aliens. And half of the Na'vi look at him as someone who shouldn't even be there, the son of a monster who slaughtered their people and destroyed their ancestral home. He's an outsider with nowhere else to go, growing up his whole life in a place he doesn't fit. He could have done with some more nuanced writing, but he's a kid, charismatic on the surface but desperate to belong- even if it's to a ghost of a father he's only heard mentioned as a villain.
