It's not the actors' fault for the awfulness portrayed in the Halloween or Nightmare on Elm Street remakes, it was the screenplays! Halloween was more about being disgustingly gory, which is just sick to watch, not scary. Nightmare on Elm Street was too corny and went too far with Freddy being a pedophile that abused the kids before he decided to haunt their dreams and kill them. Rooney Mara and Jackie Earle Haley are obviously too awesome at acting to be blamed for the crap that went down in that film.
Maybe the remake of Carrie won't be crap, but given the countless amount of shitty horror remakes, (other than Halloween (2007) and Nightmare on Elm Street (2010)) look at The Omen (2006), Friday the 13th (2009) and The House of Wax (2005), we shouldn't get our hopes up. It's better to be pleasantly surprised by a spectacular remake than morbidly disappointed by one. They have cast Chloë Moretz as Carrie and she's a fantastic actress. We shall see, we shall see.
