Pros: Well edited, no major discrepancies in the story, some interesting ideas
Cons: There are essentially 5 rooms in this dungeon crawl that are supposed to constitute 4 hours of gameplay, primarily in combat. If your characters are lvl 5, the combats may be appropriate, but any other T2 characters will easily overcome the monsters, even with encounter adjustments. The combats are what are intended to take the majority of the time so, if they go by quickly, the adventure will be very short.
The ending involves opening a door, which then leads to the next adventure in the series. This is very unsatisfying as an ending for characters, since they obviously will want to go through the door and can't. There's no climactic battle or RP encounter, so the ending doesn't feel sufficient.
Overall, there just isn't enough content for this to be a 4 hour mod or to really justify the $5 pricetag.
