As I said, I was going to see if any names cropped up connecting the films in my 100 Great Scenes in 100 Not So Great Films list.
There aren't really.
There's a cluster of not so good Marvel films, which are linked by the usual suspects (Stan Lee, Avi Arad) as producers. Then British creative types linking some of the others. I do feel a little mean about having mentioned John Carpenter's Vampires, because you can see that it had far fewer people involved and was a smaller production (and, as I said, it makes me cry every time).
