Of course the intro is the way to go.
The album kicks ass. It was an experiment, but it was a good one. Maybe some lyrics here and there are trying too hard to be evil and scary, but all in all the album is wonderful and obliterates the poor "comeback" album that followed.
Ironically I think the least convincing songs are the happy ones, the ones supposedly in "true" Helloween style. Everything else is brilliant!
