Okay, I'm roughly 5 episodes in and I'm finding it... Hard to watch. Not that it's bad by any means, it's just a bit... Like, the characters do silly things. I am finding myself cringing a little at some of the things the lead characters are saying and doing. A lot of the time, I'm able to predict how scenes will turn out before they happen. Korra seems overly confident, which is fine but... She just gets herself into situations that are way over her head, and does things without totally thinking them through first. It's a little aggravating to watch, constantly thinking to myself "Uuugghhh no, don't do that. Why would she do that?" or "Stop talking, stop talking, stop talking".
I'm also finding this show to be a little more intense than The Last Airbender. Not that there's more fighting, per se but, the whole atmosphere seems darker. Maybe it's the era and location... I dunno. The Last Airbender seemed a little more innocent than LOK is turning out. I'm going to try to watch a little more but, it is stressing me out a little hehe..
Edit: Watching episode 8. Korra's doing something stupid and, in turn, I let out one of my most annoyed groans of my life.
