Really?
Talk about your wasted use of film!
A movie made about the events that took place during a sea voyage of the doomed ship Demeter? Anyone who has read "Dracula" knows exactly what happened to the crew and the captain. Dracula feasted on them at night, eventually killing everyone on board.
There is no last minute rescue. There is no happy ending. EVERYONE ON BOARD DIES!!! (Except DRACULA!)
