Opinions on Dracula by Bram Stoker?

[Spiral]

I started Dracula a few months ago but I'm not getting engaged with it really and I'm kind of stuck, now in the part where the Demeter arrives, wanting to read other things (Marked to Die particularly and maybe Melmoth The Wanderer, despite it being long). I like the idea of the novel and some descriptions but I'm not sure I want to keep reading it and it feels very long (I love some long books but they have to engage me quite a bit), but I feel as a horror fan it's kind of a duty to read it and I am looking forward to a few things that should happen later from what I gather.

Would you recommend I keep up with it in your opinion? would I be "missing out" if I didn't finish it? maybe I could keep reading it at a glacial pace.

What are your opinions on this novel and it's importance on horror/weird fiction?
