Since there is a "best album of all time" thread, there needs to be a "biggest FAILS of all time thread" since Metal is about seeing results and eliminating the weak. So post ONE and ONLY one album that you think is the biggest Metal turd ever, and I'm not talking about a "floater".

My vote is for Slayer's Divine Intervention. Any teenage Pantera groupie could have written this.

I dunno about a fail album but surely Metallica's moans about Napster is a fail?

I honestly don't know about all time. Most recently for me, it was 5FDP's new album. :/ that sucked.

No offense, but I think that all-inclusive PC attitude has no place in Metal. I think there is such a thing as "fails" in Metal and it occurs either when a otherwise quality and influential band no longer has anything to say, or runs out of ideas, or gets jealous of s***ty bands receiving praise and success and sinks to the lowest common denominator, as in the case of Metallica.
Edit: This was to Asmodeusgirl.

meh, metallica whine about f***ing everything

I could have just said Metallica's S/T (black) album but that would be too easy. Cold Lake by Celtic Frost is another one. That must have been their "Hey! Look at us! We can play cheesy arena hair metal too!" phase.

Yeah pretty much fails in metal are usually when bands sell out.

Def Leppard.

Iron Maiden's No Prayer for the Dying, especially the song Holy Smoke. That was a huge disappointment.

In terms of albums?

Reload. I would have said St Anger, but after Reload they could have s*** in my stereo and I wouldn't have been surprised.
