I completely disagree. You shouldn't just like a show because the characters are "like you" or dislike it because they're "not enough like you." I think the fact that the characters are a specific type of girl in Brooklyn makes it all the more realistic and gives it that voyeuristic feel that makes it so interesting. This girl has written about herself because that's what she knows - she probably doesn't or didn't have an interracial group of friends so she didn't write about it - and that's what makes it so good. Because it's real. Painstakingly real at times. I think you totally missed the point.
If you want a show about girls who aren't white, write one - I'd love to watch it if it's real and honest and smart. And I wouldn't criticize it because the characters are not like me. I'm a white girl and the characters are absolutely nothing like me. Nothing. But that's partly why I liked it.
I'm an OB/GYN and frequently diagnose women with herpes. This is such a great perspective - I plan to share this with my patients. Thank you!
