Pros:

+Very original
+Very fun, completely crazy and hard to figure out
+I just played with friends and haven't laughed so hard in quite some time.
+the area where everything is turned on its side is just brilliant. 

Cons:

-numerous texture issues. Some of these improved after verifying cache, but some continued. All of us had to do something tho make it work right.

Conclusion:

I haven't had so much fun in quite some time. There are more polished campaigns around, but for some sheer crazy fun, this was awesome.

Pros:

The surprise moments
There's something about Dr. Boo's visual style (here and his parts of Night Terror) that I just love--something about the extra color that's kind of too much but I really, really love it. It's visually creative in a way I find very satisfying.
Mix of scenes. 
The finale was absolutely crazy the first time I played it.
Great sounds

Cons:

I have to replay and see how much this is always an issue, but it's easy to miss certain sounds and cool visual things if your party spreads out a bit. So it's worth replaying just to see and hear stuff.

I might like a bit more!

Conclusion:

I really love this campaign, and congrats on having it featured so I'm likely to be able to play it with some different folks.
