Because of a lot of the hype surrounding this film I went into it with expectations that were too high for them to reach. In the end I actually ended up turning it off and it took me 2 days to finish it. That isn't to say that it is a bad film because it isn't, I just felt like it was basically exactly the same film as Brahm Stoker's Dracula with Keanu Reeves from the 90's.
I'm happy that it wasn't a CGI nightmare though, and overall I would say that this is worth seeing for the right person in the right mood.
