I'm a huge fan of Bram Stoker--he was another one of the inspirations for my current novel project. The way Stoker described Transylvania was intense, as well as vivid, and really sucked me into the story. I especially enjoyed the parts Jonathan was locked inside the castle by Dracula as a prisoner. However, the parts I found most interesting were, for one example, where Dracula summoned a pack of wolves to kill the woman who'd come to his castle, begging for the return of her son. In general, I enjoyed all the parts Stoker showed Dracula's vampiric side. I actually laughed at the part the count had seen the drop of blood on Jonathan's cheek (he was shaving), and nearly lunged at the poor fellow to consume it. And Renfield was hilarious, especially when he would go into his made ravings about his master--or when he would eat a couple of spiders, or insects, much to Dr. Seward's dismay.
Funnily enough though, the Count wasn't even my favorite character. He was a cool character, don't get me wrong, but for some reason I enjoyed Lucy Westenra the most (I still chuckle every time I hear or think about her nickname, the "bloofer" lady). It upset me when she was bitten by Dracula, and in the end Dr. Hellsing had had Seward kill her (I believe it was Seward, but I don't clearly remember). But I suppose it was all for the better, considering Lucy would have continued draining all the children of Whitby's blood.
The only things I didn't particularly enjoy about this novel though, were the long, long, long, long blocky paragraphs of dialog between Mina and Dr. Hellsing, or any character for the matter. A lot of it contained unnecessary information that really didn't move the plot too much (something I'm terribly guilty of) and succeeded in boring me half-to-death. However, once Jonathan returned to England, the plot picked up, especially when they began hunting down the count. Then I couldn't put it down.
