Ooooh, okay I thought you meant the new show that just came out when you said remake.
I thought the 2013 one was very mid. I agree that the characters are definitely better (outside of the mom who I thought was more of a caricature in the new one) but otherwise it felt like they tried to "marvel"-ize it.
Now when Carrie is doing her telekinesis stuff she has to move her hands around like a superhero. The lighting was much flatter. The character blocking was a lot weaker (most noticable in the "why didnt you tell me scene" at the start and the ending confrontation with the mother. In the original the character "in charge" is literally standing over the other as a show of power and it really displays to the audience what is happening while the remake has them constantly eye level to eachother).
Ive heard good things about the TV show but I haven't gotten to it yet. Im very curious to see how it expands on the story when making it an entire season.
Edit: also worth noting that his asking Carrie to the prom is his GFs idea in the 2013 version as well but they do make it clear that he agrees with that decision which is a big improvement IMO.
Also forgot to mention that Billy is an asshole in the 1974 version but in the 2013 version hes comically evil which makes him far less believable as a character and turns it into silly territory.
