I've never read Dracula as a novel before, so it's hard to tell how well this holds up, but as a story, it was pretty entertaining and the art style fits the sombre tone well. As a tale, it does take some slightly unusual twists and turns, and there was a lot I had misunderstood (or just missed) from popular retellings of the story, so it felt surprisingly fresh, even if some of the language was a little awkward. I think a graphic adaptation probably loses quite a lot of the creeping horror of the original, simply because much of the sense of foreboding and imaginative unease has been replaced with someone else's imagination, but as an entry to a classic it was a fun enough read.
