Area that was biggest waste?

This place is so useless and such a waste that no one even remembers/knows about it:

Twisted Aqua Road.

I have never quested there, but I would be willing to retract my statement if someone can tell me it has a good story or is more than Kill (Too Many) Numbers of X Monsters that I looked at and said, "Nope."

I liked KFT's quests and Omega Sector's weren't horrible, by comparison.

I completed Twisted Aqua just for completion's sake, and it was awful.
