Seriously, who are these people even trying to kid? If the show isn't outright shit, then it's going to be mediocre at best. Hayden Black and anyone else who thinks that Gen Zed is getting flack for having the first major trans character ever is deluding themselves. Gen Zed's problems have almost nothing to do with its inclusion of minorities. It's the bland name that isn't descriptive, snappy, clever, or even particularly relevant to the subject matter; the contrived, cliched set-up (four "wacky" people have to live together!); the lazy, unimaginative, one-note characters; the subpar voicework; the lame, forced attempts at humour; and the terrible art and animation.
It's possible that the writing will prove to be at least competent, since we've only seen the trailer, but I highly doubt it will. Shona's entire identity, it seems, revolves around being trans and almost nothing else (like real trans people, right?) -- and if your "representation" is so utterly paper-thin, then that's no representation at all. In any case, even though most of the characters are borderline offensive in how incompetently they're handled (Cameron can't rap! Who knew that every black person wasn't interchangeable with Kanye West?), all of them are hollow shells with only two or three traits to define them. They're just so nothing.
One of the biggest red flags for me was how they describe Huey as a "psychopath" in his written description, but then as "psychotic" in the trailer. If they didn't bother to do the cursory research required to distinguish between these two hugely different psychological conditions, what does that say about the level of effort they put into what's supposed to be this guy's defining characteristic?
I'm not fully convinced that this isn't some kind of scam.
