This is a new Metallica. Though Lars can depict everything as a progression curve, for him, Black is just something after Justice. However somewhere along the journey Metallica became older, accepted, embraced by the rock world, and the attitude they had for the first 4 vanished. It would vanish sooner if Cliff didn't die.
I see this as a transitional album. It has the musical ideas of Justice but not the attitude. Half of this album's riffs and grooves are based on Harvester. This album is also quite vocal driven and the vocals suck most of the time. I don't like in between thrash of the 80s and singing of the 90s Hetfield, he sounds like an obnoxious cowboy.
Unforgiven is the only thing for me that came out of this period like a gem. Roam is another. Again about Hetfield's delivery, when he sings on this album about "himself" it comes out great and sincere. When he sings about "me" it's so fucking cringy, Enter Sandman, Of Wolf and Man, Don't Tread on Me, Sad but True. Really like children's horror movie soundtrack where a "tough guy" tries to get me scared. "while YOU sleep".
