To illustrate the thread topic, I'll use that wacky ghost Beetlejuice (I know that's not how it's spelled in the movie but I don't care so bugger off). For a movie named after him, it struck me that Beetlejuice only gets three major scenes while getting relegated to the background between them. I understand that they can't have him turn into a snake or whatever else every scene but from my memory, Beetlejuice seems to drop off the face of the earth for good chunks of the movie.
