Cool, I listen to gothic metal too (well I guess that's obvious now
)... tho I do listen to a lot of genres (a lot of metal genres, but also other music genres). Tristania has great songs as well.
I do recommend you see the film. There are many adaptations, but the one from which Theatre of Tragedy took the lines, is from 1967 I think - no cool effects in the film obviously, but really well played.
