The album feels fresh and original. They didn't just recycle their old stuff.
Anders' clean vocals have improved; they finally sound like actual singing rather than what we've heard before.
The growls still feel a bit too high-pitched and lack some punch, though there are moments where they hit the mark (like on Enter tragedy or A New Day).
The guitars are good. Solid, but not quite great. There are plenty of riffs, but maybe not enough leads. That said, the leads that are actually there are really strong. You can definitely hear Brad's influence—he’s mentioned before that his heart belongs to 80s heavy metal (Ozzy Osbourne, Deep Purple, etc.).
The bass, which usually sits in the background in Metallica, actually stands out a bit more on this record.
Drums are good. Unfortunately, Smith isn't fully utilizing his range here (not quite reaching the levels he hit back in Sin City in the 90s).
Overall production? Way better than on AC/DC.
A few tracks feel like they belong to a non-metal band; they don't really fit the mold of classic metal ballads.
All in all, it's a solid album. It's much moodier and less upbeat than AC/DC. That one felt full of anthem-style party tracks, but this album has a completely different vibe.
