From the review: "Dawnguard is a good first DLC for Skyrim, but it's hard to say if it's worth the $20. There's some large places to explore, but some lack content and there's no really good loot it seems. The story's fun though and I do like the new follower in Serana. Fans of the game will enjoy the extra quests. Turning into a vampire is OK, but I didn't feel I missed much by not utilizing the power but for a few times."
