Query: What happened?

I thought the CD was very repetitive. I'm a very very big Metallica fan and couldn't believe what I was hearing. It sounds as if they were going towards a harder heavier metal but just couldn't reach it. I'm lost for words. There's some interesting songs in here, but I love their old stuff and wish they'd go back to their roots. If you like Metallica go ahead and buy it. You may or may not like it. But I wasn't impressed. Next CD needs to be better.
