I've seen ads for this movie and I have a couple of thoughts.

First off, having a tail end of summer release shows that the studio has no faith in it. Second, while it's a good premise for a horror movie, those who are familiar with the original novel know how it ends: the whole crew dies. But given how many books, movies, and TV shows featuring Dracula have deviated from the source material, I won't be surprised if the black and female character survive. There may also be a final scene of them meeting Van Helsing to tease a sequel that will never be made.
