I liked it, though I read it a long time ago. The movie isn't wildly inaccurate, but the tone is different, and Tom Cruise isn't how I pictured Lestat.

Someone that I want to mention, mainly because it might interest someone who read the book or saw the movie: there is a recent anime The Cast Study of Vanitas, that is strongly influenced by the book. There's an obvious Lestat character, and an obvious Louis character.
