That pretty much characterizes anyone in middle/high school. I guess they could have made him emo, but it's not a very intricate spectrum in general.
Actual good character writing captures individuality in a universal way.
Here are short descriptions of black dudes I knew in HS:
6'6 class clown from the suburbs that plays on the basketball team even though he sucks, plays practical jokes all the time, teachers love him - becomes a local professional rapper
Chubby, anime loving nerdy stoner from a poor family who skips school to play video games, loves to debate - joins the army, loses a bunch of weight, gets really into import car tuning
Very popular church kid and athlete who gets his gf pregnant at 16, starts moving drugs for the town dealer, gets arrested, kicked out of school, and has to enroll in the alternative highschool program. Takes care of a baby, and lives with his cousins, because his Christian parents are ashamed of him - becomes a mechanic that everyone know sells weed
A tall & skinny guy mixed race guy who is sullen, listens to rap on headphones all day hates school, lies about ridiculous things, steals for no reason, but loves to talk about music - gets arrested for shoplifting and resisting arrest, gets addicted to drugs in jail
All of those people were interesting and dynamic, and none of them fit these lazy character molds from tv. I'm not saying you have to keep the sharp edges for a comedy, but the characters should be original and authentic as possible.
