Well, I suppose I can see where someone could perhaps have a healthy skepticism when it comes to Grahame-Smith's remark that all the different elements in the film work well together. It's true that he's not likely to say that they're awful together. And saying they work well together is a subjective reaction - and one coming from someone who worked on the film. Taking a wait and see attitude there could be prudent. However, I don't see any need for doubt when he says that "campy" is the wrong word to describe the funny elements in the film (after all, he wrote them, so he knows what he intended and, as someone who has seen the film, he's also seen how the lines have been delivered and the scenes have been played/edited), or that along with the funny elements there are also bloody elements and some very classic horror elements. People are more than willing to wholeheartedly believe that when those connected to the film say it's funny, they're being truthful - so I don't see any need for doubt that when Grahame-Smith says the film is scary, bloody, has moments of classic horror, and it's not campy, he's not being equally truthful.
