Death Magnetic isn't bad, some of the riffs will sound really unoriginal like they were put there just to fill the space, and other riffs are pretty sweet. I donno, I've enjoyed listening to it, they're not duplicating their old stuff it sounds like modernised thrash. Every genre's sound changes quite a bit over 20 years, bands like Testament, Exodus and Slayer are still making thrash but don't sound like they did in the 80's. So yeah I just listen to the album and take it for what it is, and I like what I hear. It's nowhere near Ride The Lightning, Kill em All or Master Of Puppets, but still not a disappointment. I'm pretty satisfied to hear them play heavy shit again.
