Definitely a Napoleon Dynamite precursor but more endearing. There's a joy about Tammy that can't quite be masked by her teenage judgment against those people she thinks can't help her be cool. Which is why her reading of Kenny Yang bothered me but made sense for her character.
Vol. II gets deeper with social interactions and develops Tammy's sense of self a little more. I think she's becoming independent without knowing it. Or maybe that's wishful thinking.
