I dunno but if I sat down to write a story I think there'd be a lot of white people, a lot of men I like, A cute gay boy that I can totally dream of and some women I like. Which would be both cliché but also with it's own touches, but most importantly, I wouldn't think about it like this. At all. I'd just write what comes to me, I'm not going to look it over for "Is there enough black people, is the woman awesome, so on so on."
So yeah, I think critique for the show isn't the right approach, critique for the station choosin' these writers however.
Edit: If I was to write a story about a Woman it'd be about my mom, A bad dauther, a minor/medium drug addict and yet a surprisingly good mother with teeth and claws fighting for her children yet fighting her own overweight and bad habits badly and a big problem with spending money wisely, spending it all on her kids and getting huge debts to both family and state, to make sure we'd all always smile, who all had their terrible problems, A schizo kid, A rebel/depressed kid(me) and a daughter born with physical handicaps having to be operated tons of times, yet staying on top of it all as a single mom through most of it. Is this Cliché?
