Weakest final album by a band?

No question at all. They legitimately were a machine.

Thinking on it, I think my biggest complaint with Now Frontier is that it doesn't feel like an album. It feels like a bunch of songs thrown on a disc and I can't think of any album they'd put out before where I would go, "It's good, but we could lose these three songs and it would be better." Even the weaker tracks fit in when you considered them as part of the whole and songs I used to hate on, say, Rage for Order, have become favorites.

Now Frontier was the first album where there are still songs I would prefer to pass over. That said, the pseudo-reunion on Tribe had some really strong moments and makes me wonder what might have happened if DeGarmo had come back at that point. It probably wouldn't have been the classic sound, but I'd bet money it would have been stronger than what we got instead.
