I think Christmas did a great job adapting Gibson's second draft. Like Hicks says, its what he was hired to do.
Would i change anything about it ?
Now that i have read it a few times and love the hardcover, i have grown to love it and would not change a thing. there are a few unclear bits in there with regards to panel layouts and what not but i think that those issues actually go well with the unrefined feel of the second draft.
I find the whole package rather charming.
