Maybe mine is an unorthodox answer, but all I've been watching lately is wrestling and anime. Still, I think RAW and Smackdown fit your question. Neither show is anything close to new, and the tactic of splitting rosters and competing against one another has been done a couple of times before, but the recent WWE New Era brand split is essentially a reset that I think could be considered new. It's brought a lot of much needed freshness to both shows, and it's been a lot of fun to watch these past couple of months.
I did catch the first episode of Son of Zorn. It was quirky, but I suspect it will prove to be a bit too offbeat for even Fox's Sunday lineup. Any promising new space operas or horror shows coming out?
