it isn't even totally the animation style, the writing is trash
I actually like TT:Go.
It was meant to be more of a looney-tunes cartoon with wacky scenarios and slapstick and songs, rather than your more story motivated cartoon, such as Avatar:TLA, which the original Teen Titans was.
Maybe that wasn't what people wanted when they heard 'new teen titans', but I don't think it was bad.
It's a spin-off rather than a sequel.
KND wasn't really my favourite of cartoons.
I liked the premise but didn't get on with the art style, particularly the character design.
