Not a great film at all. It is interesting to have the count in the 20th century, but he does not belong in it. He needs to stay back in the 1800's, as Stoker meant him to be.
This film is also confusing in many ways. If it is indeed a sequel to "Horror Of Dracula", then how did the count come to be? In "Scars Of Dracula", he caught fire and fell to his death, leaving nothing of himself (presumably). And, being Professor Van Helsing was not in any of the period sequels, how did they fit this story in about he and Dracula fighting one another to the death in 1872? Did this happen in one of the films when we weren't looking? Very unlikely.
At least Peter Cushing returns (finally) as a descendent of Professor Van Helsing. Too bad he could not have been in the four previous films.
As I said, this one is not worth watching, unless you're bored. And if you're bored, this film will add to it.
