Metallica has been going in a downward slope ever since Metallica (self-titled) until St. Anger was the nail on the coffin. However, don't let that change your thoughts to get this album, even though it may seem a bit intimidating.
8 songs, all which are over 5 minutes? This is the length of a normal cd once you listen through, it will be your money's worth, not to mention if you are getting tired of bands that don't provide guitar solos, here is your choice cd.
The topics in Master Of Puppets are quite wide assorted, some are about politics, another is control by a mightier being, the perils of war, etc. all of the songs are interesting, unless you don't like Orion, which is an insturmental.
Now, just because there isn't a parental advisory sticker on it doesn't mean that it is bad, that it is the brain of a moron. At least try to listen to this with an open mind and if you can't you can't handle this genre of music.
