Skyrim - Dawnguard DLC Reviews Roundup # 3

Some more reviews for this DLC has been written. First up is GamrReview 8.3/10 
A quote from the conclusion:

While some aspects of Dawnguard don't quite live up to the legacy of Oblivion's Shivering Isles expansion, which added massive new locations, it's hard not to recommend Dawnguard to fans of Skyrim. Not only is the quest line offered easily the longest in the game, it's also one of the most engaging, and there's plenty of side content as well. 

And the second one comes from Xplay who has a scoreless, yet very positive video review.
