It's not like she's already irrelevant in 2023 and most people have to be explained exactly who she was, from 2015 to 2018, when she was relevant.
But her voice is so good for cartoons! Except that it isn't, she sounds like my grandma who smoked 6-and-a-half packs of Kools per day, yeah great choice for a star/voice character actress. At least Sia had a good voice.
I thought the Kenan episode was the worst form of television ever created. I was wrong. It's this, it's Halsey Irrelevance on Scooby Doo.
If you're wondering why this show was canceled, watch this episode. Then stop wondering. And watch a different episode, like Batman or Malcolm McDowell or Sia. Those are good.
