I thought it was a pretty good area, but my b/f felt the same when playing through it...he thought it was way too dark and he was delighted to see the trees and forest when exiting the underdark.
But you have to admit there are some pretty good quests and some amazing items to be found
I hope you still enjoy the game, you sound pretty pissed off
