"from the director of Cloverfield..." isn't going to sell it, sorry. Matter of fact, unless they totally butcher it, you're basically taking an audience's expectation of a big monster movie and giving them what's suppose to be a "quiet" horror film--and they will hate it as a result. Not to mention the director, Matt Reeves, hasn't done anything to deserve a fan base. "Ohhhh! I can't wait for the next Matt Reeves film to come out!!"
