The movie was fun to watch. I'd have to agree it was as close to a CV movie as it ever got.
About the Dracula movies, I don't remember in which one it was... Maybe in Coppola's, maybe in Dead and Loving it, maybe both, they cut some characters and made major plot changes, which annoyed me.
I hate when they do it in movies. They make a book-to-film adaptation, then change stuff. Cutting out insignificant parts of the plot is reasonable, since they don't always have time to show all the events in the book. But sometimes, especially in older movies, they remove entire characters from the plot to save $$ on actors.
I remember that when I watched Troy I was incredibly annoyed by how they minimized the role of Odysseus so he wouldn't overshadow Achilles (Brad Pitt). Now that's blasphemy! Odysseus was the big hero in the story. After all, he's credited for creating the Trojan Horse.
