I share your sentiment, Carlos!
I don't even have the slightest desire to pick up my radio promo, let alone even buying this. Listening to the samples, I just don't think this was executed well at all, for many of the reasons you're mentioning and even more. Like the actual arrangements and performance.
And I will probably never ever get accustomed to Deris singing the Kiske tunes. That guy just doesn't have the range. Plain and simple. Every Helloween gig I've seen, Deris sounded bloody awful at the Keeper tunes. Kain hansen doesn't have the Kiske pipes either, but when he breaks out into staples like "I Want Out", he sounds sooo much better than Deris, it's not even funny.
