Debate: Metallica - Return To Form or Still Lost?

Metallica releases their new album, Death Magnetic, today! It's bigger, badder, and heavier than anything they've done in a long time. At least that's my opinion; read my review here.

I've obviously posted my feelings on the subject, but I'm curious to know what other people think about the new album. Is Metallica back to their old selves, or are they still missing the mark?
