I thought it was probably the best of the Angel mini series thus far, though I am kinda between this one and the curse. I think Aud Lang Syne suffered badly from being after Old Friends, which had a similar concept, and while it was definitely better (Old Friends sucked), it didn't feel particularly new. There are far better ones out right now from IDW, specifically the Character spotlights, and the 3 Spike one shots. Masks was hit or miss, but overall it was good too.
