Wow, it takes balls to say they don't suck.
I think they're decent, but it's pretty fucking blasphemous to say they're better than other BM bands. I'd agree Dani is a good lyricist, but certainly not the best. It depends on what style attracts you. I think the man has a bachelor's in English, and he has a good control over the use of archaic english, but I don't like his themes.
Listeneable, not awful, not amazing. I really don't see why people hate them so much either, apart from Dani Filth being all homo on stage and in videos. Their music can't be that offensive, a lot of it does sound similar to symphonic BM.
