If you can hear a strange squealing sound then do not threat, it's only the Avatards sounding off their glee, me included.
[link]If you haven't seen the "Avatar: The Last Airbender" series yet then you really ought to. It was beautifully animated with a brilliant story and is a million times better then a certain live action adaptation that I hear was made (although this could just be a vicious rumour. Like anyone would actually give a light-hearted kids show to M. Night Shyamalan >.>

I know spin offs are rarely as good as the original but I'm still looking forward to whenever this gets released. I just hope that when they describe Korra as "a passionate, rebellious, and fearless teenaged girl", they don't actually mean that she's going to be a generic, unlikable action girl. Mike and Bryan's characterisations tend to be strong though so here's hoping for an equally strong sequeal!
