Pros:

-Made me jump!
-Some hidden areas
-Pretty large mansion!
-Excellent length
-I do think I noticed some new sentences coming from our survivors!
-Excellent environment effects (in the castle. glowing rooms, floating objects).

Cons:

-Felt like the part inside the mansion ended too soon :(
-Didn't like the gauntlet run finale, wasn't as intense as some other finales I've played (personal opinion though)
-Was saddened that I didn't actually fight a ghost :(
-Some of the ghosts weren't as scary as they *could have* been

Conclusion:

I saved this campaign for playing on Halloween and it was awesome! A must play! Only argument here is that the finale felt a bit too sudden. I played with bots, but I'd definitely suggest playing this with friends if you can!
