I like it too
It's got slightly goofy lyrics and a slightly goofy feel but then again stuff like "Phantom Lord" could just as easily make people laugh. "Leper Messiah" and "Trapped Under Ice" really are the weakest songs on those albums.
Metallica's 80s low point is sadly the Cliff tribute, "To Live Is To Die." ZZZZZZZZZZZZZZZ. 10 minutes of bore.
