Some suggestions for the show
The past characters from the show should have NEVER been mentioned. It makes it cheesy. These kids would have been like 7-8 years old in 2012 (when the show ended) - they wouldn't care or know about ''Serena''.
I'm surprised not to see more characters with multicolored hair, facial piercings - those are HUGE among Gen Z teens. I know they have a girl with a shaved head but a couple of other characters look literally plucked from 2007.
Not enough Gen Z slang. These characters sound too ''Millennial''.
