I'm going to review this as if it's the first season, a second isn't confirmed as I'm writing this - although I understand the show has been relatively successful (as much as we know).
Sydney, (Sophia Lillis) an awkward high school girl is coming to terms with the suicide of her father, her burgeoning sexuality and the fact that she might have some telekinetic powers. Her relationship with her best friend Dina (Sophia Bryant) is suffering as she's begun a relationship with jock footballer Brad (Richard Ellis). Though she too has started to spend time with her neighbour Stanley (Wyatt Oleff).
I really loved "The End of the F**king World" and this show comes from Jonathan Entwhistle who was the creative force behind that one. There's sort of a similar aesthetic. It has indie movie sensibilities, a wonderful 80's inspired soundtrack and an out-of-time sensibility, from retro clothing, cars and technology. It also shares the idea of a character narrating humorously over the action. The major change is a shift location, across the Atlantic. The shows consistently funny, in that lofi sort of way and Sophia Lillis is fantastic as the lead - as she was as young Beverley in the "IT" films. I also really like (and this might seem an odd thing to say) that the series was so short. There are seven episodes, each at around twenty minutes. We finished the show in a couple of sessions.
I would say, that there are a lot of shows on Netflix at the moment that mix the idea of teen angst with a supernatural or otherworldly aspects - presumably all stemming from the success of "Stranger Things". I'd also say, I wouldn't be too disappointed if that was it. Though I really enjoyed it, threading the needle on a second season would be an amazing accomplishment and is, therefore, a risky one. We'll see.
