Yeah that smash scene was really good. They can really do stuff in these novels (comics sounds a little childish here) that they wouldn't be able to do on the show. I also thought...(whitened out as potential spoiler)
that the start of part two was a great flash back to Graduation Day part2 and Buffy and Faith's relationship. It may also explain that cover for part 3 as well. Yeah Part 2 was great, okay not as strong as the first, but the story had to be layed out in part 1. Part 2 carried on and it looked into Faith's relationship with Buffy and how that could be potentially like this one with the slayer she has to kill. Plus I did think for a moment Faith (or should that be Hope? 
) did have amnesia from the fight with the gargoyles, and was going to forget who she was. That could have been interesting. Plus I'd love to have seen Eliza in that dress and heard her English accent. 
Looking forward to part 3. Don't have to wait too long now. I hope.
