The introductory section of the adventure is fine, but the rest is incredibly bad and obviously phoned in nonsense. The final random table entry reads to the effect of, "12. I'm bored with these stupid pointless tables, you think of something."
The first few rooms are pretty interesting, and could probably be salvaged or just set to work on their own without the rest of the dungeon. The majority of the dungeon is winding, useless hallways (attempting to draw these was excruciating, and eventually we just started narrating everything.) Everything in the remainder of the dungeon is a pointless death trap with no possible purpose, theme, or use. The players have no reason to explore the dungeon and no way to understand any of it. My players would later state they preferred the Tomb of Horrors... read into that what you will.
After the initial amusement of murdering children wears off, the children themselves are agonizing to combat*. No one wants to sit around slogging through one hundred of the same, boring enemy (children.) Attempting to group them up so that a large number of them could serve as singular enemies would ruin their primary mechanic.
- Protip: Don't play this module with someone who just miscarried.
