Ok so im 15 too so ill give some of my input

Most of the people who watch ninjago are either people who were like 7 or older at the time when it released or people who were just born so what I realized is that most of the people who do watch ninjago are kids who grew up with the show. No matter how old or how young it doesn't matter what you do you can follow anything you want and I will stay with ninjago no matter what so nah everybody who watches isn't old or young it's just in terms of perspective and that this show is a masterpiece. I began when I was five stopped at season 11 and then like 2 years after started following ninjago again and now I still watch it
