I'm not buying it yet as I've just bought myself a bunch of other bethesda RPG games but at least I'd like to know if Dawnguard is good or not.
Is the community disappointed?
I personally just loved it. I was level 43, Nord with sneak, archery, sword and shield. I thought it was wonderful, beautiful, breath-taking, and scarry at times. There is anticipation, thrills, adventures, ups and downs. Not to mention how many times I picked my broken body up off the ground and had to re-do.
