Common Sense Note
Parents need to know that Dracula takes heavy liberties with the plot and characters of the classic novel that inspired it, dialing up the violence and sexual content for modern audiences. That means you'll see plenty of bloody acts (like throat-slitting and flesh-eating), but cutaway shots keep most scenes from getting too gory. You'll also see characters engaged in sexual activity that, while simulated, is strongly suggestive. Characters drink socially, too, and some use hallucinatory drugs, although language is comparatively tame (such as "damn" and "hell").
Although sexual acts are simulated and no sensitive parts are shown, some scenes are heavily suggestive with lots of skin that stops just short of nudity.
Death, and blood, are integral to the plot, and when characters die, it's carnal and messy (slitting throats, devouring necks, etc.). There's physical combat, too, involving low-tech weapons like knives, crossbows, and stakes.
Light use of gateway words like "hell" and "damn."
Dracula and Van Helsing -- once sworn enemies -- are working together for a common cause. That said, the common cause is killing people who once wronged them, and achieving their goal calls for large-scale treachery, blackmail, and deceit.
Drugs / Tobacco /
Mostly social drinking, although there are minor characters who use hallucinatory drugs.
