Totally not a knock off of Harry Potter. This was actually one of the series that JK Rowling took inspiration from as the books were written in starting in 1974. There has been changes made to almost all adaptations but I found the 2017 series on Netflix and couldn't help but get sucked in. Originally, I was skeptical as I didn't have much interest going into the series. I was expecting something which left me bored or questioning the writing but at almost every turn I found the show to grow on me more and more. I'm very much looking forward to season 3.
