I don't generally watch TV. The last series I followed was probably YuGiOh until the start of GX and Pokemon through the start of the DS series. And Futurama reruns.
I'm watching Gravity Falls [right now] and it's pretty funny.
I saw an episode recently of Lego Ninja Warriors Fighting a Lego Snake-Creature Army and Lego Pirates and I wouldn't call it the worst show I've ever seen.
I also saw an episode of Ninja Turtles and I think they've changed the origin story.
