Much better than I'd hoped for! The art throughout was quite good, and and fairly stylized.

Having the Robin book "narrated" by Alfred worked very well, as it highlighted the contrast between the way Batman and Robin approached crime fighting, and also allowed us to access a conscious. I've seen too few books of this nature address the morality of having a teen fight crime as he does.
Despite that, many of the scenes with Robin (especially early on) were humorous, and kept the book a little lighter than it could have been.
As I said, I enjoyed the artwork, especially the way Two-Face was "shot" in various scenes.

The Batgirl portion of the book was also entertaining, but with the potential moral questions lessened. There was quite a bit less buffoonery, but I enjoyed the humour in Barbara's inner monologue. The Batgirl/Robin interactions were very entertaining. I'm a fan.

While the two halves could easily work on their own, I think the melding of them into one collection really added something.
