Look, I'm 62, and this series is definitely not targeting me. I'd say it's targeting 20-something women who want to watch spunky heroines overcome odds and have sex. And that's fine, because that's a market.
Even though I'm old, I do like some youth entertainment, like Euphoria or Impulse, but Good Trouble is pretty bubble-headed. I only took a look because I'd seen glowing reviews, but I found it pretty intolerable from the first 5 minutes.
Still, the thing's got lots of energy and cute leads (who look like high schoolers to me because everyone looks so damn young nowadays). So I won't say you should watch it, only that *I* shouldn't watch it.
