I think the whole cast was wrong and I found the whole thing anoying. I just couldnt wait for Lestat to die 
So... a disappointment right up to the very end, then?

I had a friend back then who didn't know I was into the whole vampire thing and who after a weekend told me that she and her boyfriend had been to what had to be the worst, the most horrible, the most pointless, the most boring and God-awful film she'd ever seen. She couldn't understand why people made such useless drivel. And so on for quite some time - I remember her rant because it *was* truly memorable. She concluded the rant by informing me of the horrid movie's name - it was "Interview with...".
BTW, I haven't seen "Queen of the Damned" so I don't know if the non-Cruise incarnation of Lestat is better or worse or just different.
