Pros:

True to Lord of the Rings.

It's own brand of Epic.

Has a goal beyond Gold.

The use of the Original survivors add to the sense of urgency that's felt in the film.

Needing to actually fall back and move to more and more compressed arenas.

There's even traps for the infected siege.

Cons:

Bots can't do jack.

Online on this map has a tendency to bug out.

I ended up with creator credits spam a few times. Not sure if server side or client side.

Awkward mix of being incredibly easy and incredibly hard. The middle ground (When the wall is lost) is too short in comparison to how long I had to spend by the Stronghold door.

Conclusion:

Very seldom does one feel sufficiently epic in survival. This just captures the very essence of "Epic Badassery" and mixes it with a giant vat of "Epic sauce" to make one giant campaign where you can not help but feel like either a God among Men. Or a fallen hero for a cause.

Pros:

It's a fish.

More specifically a salmon.

More more specifically, a Steelhead Salmon.

The sounds make me giggle. :3

Salmon v Tank now possible.

Even better; Witch v Salmon.

Cons:

It's not a Coho salmon, or a Sockeye, those things have amazing derp faces. No points docked.

Conclusion:

You have little idea to just how long I have waited for someone to do something like this. When I first saw this, day it came out, it went into my game and never left it. Mr. Lanky, you are my hero for L4D modding.

Pros:

The third map is the best map I have played in anything, ever, in all time.

It feels like an actual "Movie".

The stoic characters sort of add to the "Foreign" feel to the campaign.

Cons:

Very little referencing from survivors, but it doubles as a pro.

The first map is just... It just feels out of place with the continuity of the last two maps.

Conclusion:

I tell everyone I know to get this campaign, specifically for the last two maps. Those alone take about an hour to complete, it's amazing.

And well, maybe explain more on how the survivors go from Ambulance to house on a mountain.

The third map gives this campaign a +150 score boost. >.>
