Pros:

-Scale of the finale was awesome
-great setting
-custom infected additions!
-Different ways to make it through each map
-Fun exploration
-Great detail - great events (challenging)
-Had living static characters in beginning (creepy sounds in beginning too!)

Cons:

-A bit short - Need more!!

Conclusion:

It is a great map to give a try.  many very detailed areas, some are ok.  A lot of places/settings you have yet to experience in L4D2!

Pros:

-nice spooky environment
-big gun on a small tractor trailer, nice addition

Cons:

-Very small
-not much to do/experience

Conclusion:

It's worth a run-through, but really not much re-playability.

Pros:

Fun map to walk through
-good detail
-lots of European flare!
-good events and pacing
-great creativity in map design

Cons:

-i loved it.  Nothing really.

-finally was easy to figure out, umm, mounted guns placed in not so useful spots.  No biggy!

Conclusion:

Well Worth A Playthrough!
Excited to try on VS!

Pros:

-Wonderful scenery and map layout.  Just awesome!
-Great detail in all features and well polished
-Very creative and well thought out. 

Cons:

-in campaign, some lull areas with little to no infected.  I didn't want to up the difficulty, just the number of infected spawned.

Conclusion:

This map has an amazing campaign with so much detail, you'd think valve was in on it.

Have not done VS mode, but going through, I paid close attention and determined it would certainly rock your socks off!
