Really enjoyable. Again, the art isn't all that it could be, but I thought Vaughn did a great job with the plot and dialogue - it still felt like I was watching the Scooby Gang. Also, very nice to see Faith again, and I enjoyed how she and Giles got along.
The one story that Joss wrote was okay - the actual plot was nothing, but the Willow/Buffy fantasy banter felt right, and the insights into bits of Willow's past (and current) were... enlightening.
