There are two downsides to getting Dawnguard: Vampires showing up at night to eat your NPCs, and an at-times clingy follower who will follow you during and between certain Dawnguard quests.

I'd still say it's worth playing, and I do like the clingy follower most of the time, but it's not all upside.
