In the first movie the mother was creepy and terrifyingly religious! I was afraid to be Carrie but in the new version the mother from the beginning always seemed weaker then her. Carrie's powers were more evident in the remake from early on. In the original she doesn't realize her abilities until later on in the movie. They changed a lot of the scenes that made the original creepy movie creepy. Chloe Moretz did an excellent job trying to live up to Sissy Spacek's original performance in the 1976 version directed by Brian De Palma. I will say the new Carrie has great visual effects and explosions that make Carrie's powers seem more real and believable.
It's the same movie just not as good I think. Some people enjoyed it like modern scary movies they have a good finish a big bang and the audiences tolerate them. For me the entire story needs to be good from start to finish.
