Pros:

- the maps get darker and darker as you go
- faithful to the books
- liked map 5; long and took a while to get into the mountains
- the escape vehicle at the end of the finale made me LOL; nice touch

Cons:

- lots of bugs (see below)

Conclusion:

The following bugs were encountered in my playthroughs:

- graphic glitch causing sky to tear at finale  (maybe intentional by map author?)
- couldn't transition across maps 6 and 7; booted out to lobby
- couldn't transition across maps 1 and 2; booted out to lobby
- safe room doors sometimes require to uses to successfully shut
- tank in finale got "stuck" and couldn't find us.  We had moved over to the sign and tank couldn't find us.  Had to run down towards the lake (to the right) in order for tank to navigate up hill and get to us.

Overall, I had fun with the campaign.  Needs a little spit and polish, but not bad for a first effort.
