Original PPG was pretty similar to Teen Titans GO imo.
Probably because the original PPG was directed towards kids as TTG is. (But even then...I don't think they're that similar since cartoons today are different from cartoons then). Original teen titans was directed towards teens and they dumbed it down for kids...I just hope they don't ruin PPG because most cartoons these days are horrible compared to how cartoons were in the 90s (only ones I like is Gumball, Adventure Time and Steven Universe...but i don't understand cartoons like the abomination known as "uncle grandpa")... I hope they don't make it too "modern".
PPG was in my top 10 favorite cartoons when I was younger, seeing this excites me and I'm glad theyre remaking the old ones everyone forgot into these new refurbished ones.
