I have had mine for about 4 months and it is now my favorite in my 5 pin collection (just passed White Water). It is just so fun. I find the call outs hysterical - I know it is supposed to be 'dark', but I get the sense the game designers did everything with a big grin on their faces. I think one tip off to this (obviously) is the Fluffy the Vampire bonus. Just hilarious.
When I can get the 3 multi balls going and can get both the Castle jackpot (SCREAMING WOMAN!) and the Coffin Jackpot (SCREAMING DEAD DRACULA!) it is just such a rush. And I am usually cackling with delight just like Drac.
