the beginning of the end for some, the culmination of a career for another but especially the album that brought me into the metal in my teens. the production is perfect (too may be), the compositions are solid but the first albums are far away. who cares, fire ships as Enter Sandman, Sad But True and others have become classics, as well as two ballads The Unforgiven and Nothing Else Matters, although Metallica did better about it since.
