GOOD THING: John Ostrander is the guest writer, in this special issue which reconciles Deadshot's origins as a Bob Kane creation back in the 1950s with the development Ostrander gave the character during his beloved (and criminally uncollected) run on Suicide Squad.
And if all that continuity speech just gave you a rash, don't worry - you don't have to have read ANYTHING to enjoy this issue.
BAD THING: This is a personal pet peeve but I am somewhat disappointed to learn that the visions of killing people we've seen in the past storyline were less about Floyd Lawton developing some sense of humanity and more his psychosis shifting from suicidal thoughts to homicidal ones. While I admit this is a lot more in-line with the way the character has been written, the idea of an amoral thug like Floyd having to struggle with unfamiliar feelings of compassion is an interesting one I'd like to see explored.
All in all, a fine issue and a fine jumping-on point for those of you who still aren't reading this, for some reason.
