The thing I prefer Korra over Last is the soundtrack. like holy smurf Jeremy Zuckman is a god. I mean I like a lot of artist. Typically i'm a fan of Bear McCreary when it comes to TV soundtracks but Zuckerman is hands down amazing.
I'd be an airbender personally, but not a nomad. I'm loving this season so far. my only complaint is that Asami's fine ass has been absent for the past two episodes.
I can't wait for them to release an Avatar live-action film. Yes, that's my way of denouncing the existence of Shyamalan's Airbender. What a sack that was...
As for bending... as a kid, I probably would have said fire. These days, I feel I could wield pretty much any of the elements. My personality is supposedly of the Element of Air though.
