Yeah Korra had its issues. I'm almost done with the first season and it's been fun in a lot of ways, but there are a few things I didn't care for. The biggest one is honestly something I didn't like about the original series either, which is how much of an edge benders have over non benders. I mean, I get that it seems pretty obvious that they would, but it would have been nice to see non benders hold their own a little more often. I'm sure that it wasn't intentional but the implication is that you're either born awesome or you're born to suck, and it was worse in Korra than in AtLA. It doesn't help that we're sort of shown that non benders generally have it crappier than benders and that the only group trying to leverage for better treatment of non benders are the bad guys.

Aside from that, there's the horrible pro-bending arc that goes absolutely nowhere and wastes, if my memory is correct, 3 episodes and serves no purpose except to provide a backdrop for one of the worst romance subplots I've ever seen.

Yeah, I have noticed that a bit in Avatar but I heard it was nothing in comparison in what they did in Korra. I heard that the first season wasn't bad but it just slowly goes down hill more and more as it progresses. I just don't want Avatar ruined for me so I never watched Korra. My friend told me a lot that I was very unhappy with so I am not sure if I will every watch Korra even though people try to push me to watch it >.<

That's about what I've heard too. From the sound of things the series will continue to have things that annoy me but I'll probably keep watching it because the good stuff outweighs it just enough for me. Kind of like with the Star Wars prequels, the main story and characters in those were pretty awful but I can sort of tolerate them because I like the universe. From what I've heard the end of season 3 and season 4 also help make up for some of the crapiness. I totally understand if you aren't interested in watching it though, for a while I really wasn't either.
