Some movies I'm okay with a remake, if it can be done better, especially if the original has not aged well. The problem is, most remakes don't strive to be anything better, and wind up being lackluster.
But Carrie is not one I think should have been remade. Brian de Palma knew what he was doing when he created the original, and did it well. Everything about that movie still holds up today, and it's still a very clever, chilling horror movie.
The problem with a remake is that it's not going to invoke anything new we haven't seen before, because the original was done so well.
You're going to get to see an entire town get blown to smithereens that you didn't see in the original......
