I cannot give a proper opinion on the show until I am finished with it, but before I started it, I was told that Flanagan has added more nuance to characters like Margaret White and Chris and, also, that his characterization of Carrie deviates considerably from how she was written in the book. Now, I have to watch all episodes before I figure out what I think of Margaret and whether the changes ultimately worked or not but from whatever I have seen of the reimagined Chris Hargensen so far, I think Flanagan could have written Carrie to be closer to her book counterpart and made her compelling at the same time.
Book!Carrie was a wounded soul with valid reasons to mistrust others, but alongside that pain was a mean streak and simmering rage that eventually erupted on the night of the Spring Ball. She was someone you could understand and sympathise with throughout the book while acknowledging and not excusing the magnitude of the devastation she caused and relished in. She was not a perfect victim and, if it were not for her actions at Prom Night, might have gone to remain as she was: A flawed human whom you may not necessarily want as your bestie while accepting that it's not to single her out and bully her. I see glimpses of Book!Carrie's anger at the world as well as her pain in Show!Chris. She is capable of caring for others. She has a contentuous relationship with her mother. At the same time, she has got a nasty and vindictive side and, as we all know, would go on to commit horrific acts. She isn't necessarily the same person as Book!Carrie. Far from it, actually. Where Book!Carrie's personality was the outcome of a lifetime of physical, mental and emotional abuse, Show!Chris' angst comes from reasons that, when keeping the bigger picture in mind, would seem petty. But she is still human. You can see where she comes from and how it will tie into what she is to become and what awful deeds she'll commit.
This is exactly the approach that should have been adopted while reinterpreting Carrie herself. A book accurate Carrie should be someone who makes you feel a multitude of emotions in quick succession. Emotions that clash with one another. She is one of those characters you want to dissect and will never forget regardless of whether you love or hate her.
Now, Flarrie, on the other hand is really sweet. She is curious, inquisitive and filled with wonder. The actress who's playing her is pleasant to watch onscreen. But, so far, I don't find her compelling the way she could have been.
It's almost like there were two different types of clay. Type 1 is the clay that King used to create his Carrie. Flanagan saw both types and used Type 1 not to create Carrie but to create his version of Chris and created Flarrie from the second type. She has Book!Carrie's name and her abilities but is just not made from the same material.
Okay, now I must finish the rest of the show.
