Movie Studio Malpractice!

I am upset to learn that the new Harry Potter movie got bumped from a Christmas to a July release because Dark Knight did such awesome business last July, so therefore all big movies should now be shown in July? I don't really get it, and I am outraged. The Harry Potter movies have always been Christmas movies, even as they've gotten darker and darker. The new one will seem silly in July. Dark Knight worked in July because it's a hot, dark movie. This then led to my new theory of cinema, which is that all movies can be placed on three orthogonal axes: light-dark, hot-cold, and wet-dry. I wanted to make a 3D scatterplot to illustrate this theory, but Excel doesn't let you do that. Instead, here is a scatterplot of movies with Wet and Dry collapsed - you will have to squint your eyes and pretend you can see that dimension. Click on the pic for legible titles.
