Which Hook Do You Like-Which Should I Write

Since everyone was so helpful with polishing my query (and thanks for all the great input), I thought I'd ask for some feedback on which idea to work on for my next novel. I've had a bit of writer's block (for the first time ever), as I can't decide which story to go with. Here's the idea's I've been toying with:

1. Kids whose parents just brought a old movie theater have to deal with the ghosts (or monsters) from classic horror films before the customers begin to catch on. -This one I've been thinking about for a couple years, but still  it's probably the least developed.

2. A fatherless family moves into a big old house that turns out used to be a mortuary. The old graveyard it boarders should have been a clue. But the problems really start when someone starts summoning the ghouls. -This one is probably the most developed of the three. I have a step-sheet mostly laid out.

3. A vampire novel told from a male perspective. -This one is probably more Young-YA (say eighth grade M.C.'s), and I've already completed almost 1/2 of it. My plan was bang it out and release it as a Free eBook when when I finally get Super Zombie Juice Mega Bomb published.
Except, I've ran into a roadblock and it requires some major rewriting. The main problem is, it might do fine if I release it as a free eBook, but pretty much no agent is looking at vampire novels right now. I think it'd purely have to be a promotional thing.

So, which one do you like? Which do you think has the most potential?
