"High School Music: The Musical: The Series" is just modern day Glee (later seasons).
You can't convince me otherwise. Miss Jen is Mr Schue. Nini is Marley. Ricky is Ryder. EJ (I think that's his name?) is Jake.
I'm convinced that they just watched Season 4 of Glee and was like "I like this. Let's use this".
Also Carlo's is 100% Klaines child whom Rachel surrogated and I stand by that. He just needed to attend extra dance classes, but the resemblance is there. He has the sass, the dream, the talent, the sarcasm. We approve.
