I disagree. Although the intro is a well-done progressive tinged clean guitar piece, the end of the song destroys it. The end of the song (I'm talking about the distorted 16th note triplets) sounds cheesy and forced.

Metallica's masterpiece is probably Orion, where the instruments display astounding lyricism.
