Stuff with a wider range of actual three dimensional characters that aren't all the usual Straight White Person fare is fantastic, but not everything with non-white or non-straight people is actually any good.
The example I always come back to of doing it right is Russell T. Davies' Queer As Folk, where the characters all felt -real-, I could imagine running into them on a night out down Canal Street and sharing a natter outside a club over a cigarette - and found myself rooting for them to be happy -because- they came across as real flawed people rather than Avatars of Representation.
Grey's Anatomy on the other hand... well it was great early on, had some up and downs, hit a rock during amd just before Covid, then recovered is now a little bit too on the nose regarding certain issues. Yes, send a pro-Choice message. Yes, highlight the hard reality of strict anti-LGBTQ and anti-abortion laws. Or racism, or the obesity pandemic. But please, don't turn it into a lecture, entertainment is not the right format for the that. A lecture is.
