If this were a live action network show, you would be right: Friday is where series are sent to die. There are exceptions, notably The X-Files on Fox – which is where everyone got the idea a Friday night show could do well – but mostly Friday is a dumping ground.
With Nickelodeon, it’s harder to tell, because since the days of SNICK, they are playing in a different field. So Korra airs at 7PM on Firdays plus a re-airing on Saturdays at 8:30PM. That seems like a bad spot, but on Nickelodeon, it’s just the spot to lure both kids and adults to the network.
There will be Books 3 & 4 – those are happening – but this Book, Nickelodeon has decided to see if people will come to the channel for Korra, instead of putting Korra somewhere where people could happen upon it.
It’s a weird decision and one that will only continue if it works, but the plus side is adults who watch TV not-in-the-morning can easily find it and people who are already fans will find it wherever.
Short answer: Yes, it seems a bit weird, but not weird enough to worry about.
