They were all well written just because one had development doesn't mean shit. Also way to simplify every other short just because you have a hardon for DEEPman. "lol I have internal conflict, and look at my play on words and symbolism" ooooohh that is amazing writing.
Deadshot was the best written one overall it showed it captured who batman is and what he stands for. He's forced to deal with the murder of his parents. He realizes that he could've just as easily been in deadshots shoes and he steels his resolve because he knows he's the only one who can do the job.
Sorry that he didn't use beautiful philosophical jargon.
