I've got the new album and I must say that although it's a big improvement over the last couple of albums, it falls way short of anything GOOD. It sounds like a Metallica tribute band trying to write their own songs, yet still copying Metallica. It's not bad (except for the drumming) but it's not good either. The riffs are generic and stale and contrived, the solos are unimaginative and boring, and the drumming is absolutely horrendous. There are a couple of songs that could pass for filler on a much worse album by a worse band, but this is Metallica.
I honestly think that they've just lost it. I know they were trying to recapture their youth in this, but it's like they haven't been paying attention to heavy metal for the past 15 years and how it's changed. I guess they still think that thrash metal is still like Kill Em All, and it's not. They had to up the ante not just with their style but with their playing abilities and they didn't do it...I don't think they CAN do it. Musicians these days are just too good and Metallica can't keep up anymore.
