What a shock

THe sassy mixed black friend that keeps it real and tells it like it is. Th nerdy DUFFY white friend that is sweet and supportive and provides the moral center.
The white ,rich and popular high school bitch bully that gets her comeuppance at the hand of the secretly hot unpopular white girl who looses her way halfway through. The Chinese sister that has mystical knowledge of the unknown.
What is the point of being obvious in stressing multiethnic casting if they’re the same old tired roles?
I don’t care if it is offensive or not. It is just boring.
