Pros:

Very detailed
Pretty neat finale
Splash Mountain yay!

Cons:

Kind of boring... 
Very few panic events
You just sorta... walk... through a semi-abandoned DisneyLand.

Conclusion:

Very cool map, just needs to have some actual challenge added to it. Thankfully, the finale is already great. Now if only the other maps were as challenging.

Pros:

Volvagia!
Sub-boss implemented very well
Beautiful recreation.
All the puzzles are right where they should be. 
Goron Tanks!
King of Red Lions Easter Egg!

Cons:

Zelda enemies do quite a bit a damage... 
Walls of fire take too long to turn on, it made solving the fire maze a trial and error sort of thing. And damn they murder the crap out of you if you stand in them for even just a second.
Falling Rocks in the final boss right OHK me... sort of hard to avoid them, if ask me.
The fire elevator from map 3 could afford to be a bit bigger to fit all 4 survivors, or just slow down the hoards for a second so teams can go up in pairs without getting over-run. 

Conclusion:

Another amazing campaign! There's some balance issues, but the whole thing is so well done they're easy to overlook. 

Pros:

Awesome stuff. Great recreation of the N64 classic

Cons:

Music could be louder. 
Some little bugs here and there, but totally passable.

Conclusion:

Great campaign all around. 

Pros:

Maps are great renditions of popular films, books, and attractions. Great set pieces and textures.
The Haunted Mansion (based off the Disney ride) is of particular mention in it's true mastery of detail, right down to the expanding room at the beginning.
Tintin map! 

Cons:

Could use an update to fix a few bugs or add even more detail.
Besides for the well-room event and the crumbling staircase room, the Mines of Maria are a bit shallow and very difficult at the end.
Bottom line, though, as a gameplay map it's only OK. The true value of this campaign is just exploring the creativity of the map-makers

Conclusion:

A favorite map among my friends and I. First L4D (2) map to really impress me on it's scope and level of detail. The Nightmare theme makes for a good ending, though to be fair it's not as "scary" as the movies/books/attractions they're based on. Still, a great campaign and should be a staple in your add-ons folder.
