Mike Flanagan has done it again. This man can't miss. From the story development and modernization, to the striking cinematography, the directing and editing that gets even more out of the actors' immersing performances. This show stands with his other best works in being near the top with the likes of The Haunting of Hill House and Midnight Mass with its overall quality. Granted I'd still say Hill House is his best work as it is simply more terrifying as what's come to be expected in horror media, still Carrie is terrifying but like Midnight Mass in a more unique kind of way. If anything Carrie may be even more unique in how it's terrifying and how it explores the question of what makes a monster and what is true evil.
As said Carrie explores the themes of morality with the main character being a sheltered girl who raised by Christian fanatics in the modern take on that fanaticism in the Christian nationalist culture where they are conspiracy theorists who turn everything into a freedom issue but the show creates and interesting narrative where they come into contact with an adversary who is bullies Carrie but in the end argues the same freedom of speech argument that you would normally see from the likes of Carrie's family. It challenges your perception but also shows frail the freedom of speech argument is because freedom for all is impossible because there's always conflict with what people want and not even in irrational ways but just in ways of opinion and outlook so the question becomes how do you strike balance between freedom and security whether that be not only of physical but also mental well being.
So I'd recommend this adaptation to any horror fan or Stephen King fan since it has his blessing and he was a part of the production of it. While it's not as directly scary as some of Flanagan's other work, it still provides a more thought provoking horror that will keep you thinking long after you finish the last episode.
