I didn't realize at the time Interview with the Vampire was a beginning of a series but the first book did not wet my appetite for the rest of the series. I found the main character, Louis, lacking in depth and the antagonist, Lestat, had too much mystery about him that was never resolved. The only character that was really explained was Claudia the child that Louis and Lestat both had a hand in turning. She would have intrigued me more if she hadn't been so cold-hearted. That's my personal preference though and despite that I do think that she was the most well written of all three. Louis and Lestat were contrast of one another. Lestat embraced his vampirism with a passion and vitality while Louis just barely accepted it, but he do so with reverence. This made him unbelievably morose and also pompous thus construction the formula for an irksome and insipid narrator. Even when the plot got interesting or down right weird I had a hard time bringing myself to continue on due to the manner of which it was told.
This was the first book I've read by Ann Rice and even though it was certainly not my favorite I would still give her writing another try. Ultimately, she used a flawed device to tell her story but her writing was clever and skilled.
