I'd say the highs are about as high as a lot of the highs of The Last Airbender, it's just that the lows are lower. They give the villains in Korra more interesting political ideologies though.

I felt that the Imperialism from the Fire Nation in the original series was a bit underdeveloped. You get traces of it in Book 3 towards the beginning, but there could have been more. For example, Fire Nation colonies in the Earth Kingdom are brought up a couple times, but it would've been more interesting for the Gaang to visit one firsthand and possibly hear their version of what's going on. Unless they did, but I don't believe they did.
