Although the series is very different from the books, I really liked it, but at the same time, for five or six episodes, I didn't understand what was happening. I think the series is made for people who have read the books and yet this is in a way a mistake because at the same time, readers usually want a faithful adaptation but this adaptation borrows very little from the books. However, I recommend reading the first two books if you haven't because the series borrows from Lauren Kate's series only the names of the characters, the location, and a very abstract idea of the book.
What annoys me, however, is that the series does not have a specific ending, everything happens very suddenly and the ending, and although I understood it because I read the second book, it seems to me that it represents a climax rather than a denouement. Although the characters don't look like I imagined them, except for Lucinda, I think the actors played very well, especially Jessica. Initially, I didn't trust the actress who played Penn, but watching over the eight episodes I think she was able to portray her very well. The atmosphere itself is very mysterious and although sometimes it seemed to me that nothing was happening at the same time there was a lot of suspense and I wanted to see what was happening as quickly as possible so I watched eight episodes in a row. All this screenplay feels more like a kind of beginning or like a kind of introduction to what should have followed, that's why I can't give it more than a 7, but if I separated the actual book from the movie, I would probably give it less. However, I understood the series precisely because I read the book, in a way it is a screen adaptation inspired by the book, but at the same time, it is not. I wish there was a new season because the CGI at least was a lot cooler than what we saw in the 2016 movie. I also loved the cinematography.
