Reading the module through, I can't imagine the amount of work I'd have to put into this piece of bore in order to make a decent adventure of the blasted thing.
Fight. Rest. Fight. Rest. Fight. Rest. Oh, and find and disarm save-or-die traps every damn five minutes, of course. Whoever builds an adventure that has a save-or-die trap in the first 100 metres of campaign grounds must be insane.
No NPC interaction to speak of, no riddles, no mysteries, no embeddedness in a larger picture, no atmosphere you don't provide on your own.
Every single monster type and subtype somewhere in there, so much for theme.
Hack it, slash it, hack it, slash it. You want your players to use finesse and brains once in a while? Make a wide berth around the City of the Spider Queen!
