Controversial opinions on metal

I agree with that opinion for sure.

Rocka Rolla is pretty great.

Also, controversial Kreator opinion: Pleasure to Kill may very well be a great (read: 10 out of 10) album, but Enemy of God is even better than that. Hordes of Chaos can fuck off though.
 
What? No.
ya brah

I dunno. I just feel that Kreator found a good thing with their more melodic, "Gothenburg"-influenced sound. Enemy of God, as an album, is just so wonderful all the way through.

Now I love me my aggressive, rough, abrasive thrash (which is why I also regard PTK as a 10/10 album), but EoG is just easily my favorite of the two.
 
I enjoy the music of Arsonists get All the Girls. This seemed to be controversial. Lets see how this goes over. . .

Arsonists get All the Girls are way better than Slayer.
 
No, a controversial opinion is one that could be debated. Your opinion there was just ridiculous and stupid; if anyone took it seriously it would be controversial but one way or the other anyone who would say that isn't worth taking seriously, so it's not. It is, instead, what we call trolling.
