The ending is really confusing. Probably the worst ending of any of Hammer's Dracula films. A big mistake, in my opinion. The ending of a film is really important. A bad ending can ruin the experience of an otherwise good movie, and a good ending can save an otherwise mediocre film.
Still, Christopher Lee rarely, if ever, disappoints. And the first half of the movie is quite good, even without Dracula (if we don't count the death scene repeated from Risen). So, good enough, but should have been better.
