Thank you for your input, it is much appreciated. Unfortunately it was a bit late, as I've already placed my order. Forced to go soley off Amazon comments, I went with 'Dangerous Habits' as my gateway issue, if you will, into the Hellblazer world. Did I make a good purchase?
Another question, is Ennis' run on Hellblazer as overly gratuitous as Punisher? I only ask because, while I love the Punisher MAX series, I've found his more gratuitous writing doesn't work all that well outside the series.
