Id day its great, its not as good as avatar the last airbender. But thats because it set a high standard itself. And i would deffinetly change some things. Like the ending of season 2 and how korra was kinda jerk in that season. But besides that, I think it was a good series that was partially ruined by the deadlines and production. Definitely a great watch if you make it through season 2. Also I think a lot of people underestimate how fast the tech advanced in those 70 years after the original series. The fire nation had steam powered machines before the 100 years war even began. So tech being around the time of korra being the way it is in my opinion very decently acceptable as possible. At least for the time...
