Seriously, it is hard to describe what is going on and still have you want to see the movie. You have the stuff in the past, the stuff in the present, the crossover of Akasha into both stories, and all manner of character relationships. On paper, it sounds like it should be interesting. It just isn't. None the characters connect on an emotional level. Not to mention everything is cut together in nonsensical fashion; there is no flow to narrative. They would have been better served focusing on one side of the story, either Lestat's early years or Lestat the rock star.
I do like the idea of a vampire rock star. I would have been perfectly happy if the movie had focused completely on the musician aspect. There are a lot of ways you could liken the vampire lifestyle to that of a rockstar.
Queen of the Damned, as presented, is not a movie worthy of time. If you have read the novels, I am sure you will agree that this butchers the source. Beyond that, it s not a good movie even when taken on its own. The characters are not well developed, the story not well told, and it is difficult to care about anything.
The story leading to the production of the movie lends a little insight to what happened to this production. After sitting on the rights to the Anne Rice novels for years and with those rights about to expire, Warner Brothers brought in writers to adapt the two novels following Interview with the Vampire (The Vampire Lestat and Queen of the Damned) into a single movie. It was fast tracked and originally intended as a straight to video release. That changed following the tragic death of Aaliyah, when it was decided to capitalize and release the movie theatrically.
One final note, Lestat's singing voice was provided by Jonathan Davis of Korn. Davis also wrote the songs for the film. I have to say it is the most distracting singing dub I have ever heard in a movie. Davis' voice is so identifiable that when hearing it linked Stuart Townsend just sounds off and very distracting.
