Aww, I love Katara! But different strokes for different folks.

I do like Zuko but I like him best being dweeby with other characters, especially his ninja girlfriend. Aang is my personal woobie for this show.

I don't think the entire country is EVIL, but the thoroughness of the propoganda as seen in The Headband and The Ember Island Players makes me think there's lots of re-education and tough times ahead for the new Fire Lord in getting his people to accept his new policies.
