Hi!
Where it is right now, in Movies-Misc > Crossovers is actually not correct. This is a catch-all category for fandoms that have no category of their own. When deciding where a crossover fiction goes, we tend to look at the main setting of the story.
From looking at it, is it going to be set in the general universe of Bram Stoker's Dracula? If yes, then it really does belong in Movies > 1 through F > Dracula.
If it's set in the general universe of Beetlejuice, then it goes in Movies > 1 through F > Beetlejuice.
The good news is that you can move it easily yourself, and all of your associated data moves with it.
