I said this, in the poll, but it probably bears mention here:
1) I hate silly in my games, as a general rule. My players know better than to use pun names, tinker gnomes, etc.
2) I hate the Forgotten Realms and would love to see it go out of print/support.
3) I hate the Underdark. It's potentially the dumbest idea from a setting I loathe.
4) I hate the drow. They may not have originated in the Realms, but they have become a boil on the nethers of the Underdark (see #3). I don't know that they're in the module, but odds are better than even.
I am totally ready to drop my cash and run this module. I can't even fathom what about it interests me, but it does. I like demons, so maybe that's it. I don't think so, though. I'd say the whimsy that was added is going to push all the above stuff I hate to the side with a wink of "It's just a game, man. Relax and have fun." It may fail to live up to expectations, but the more I hear, the more I'm interested.
