I've read the first story arc, not reading the second story arc because I sold off my issues before I had the chance, and also I didn't have the whole story arc and didn't want to leave myself half way hanging, so I've read the first 9 issues or so.
I'm probably not the first one to say it, but Red Hood And The Outlaws is NOT a good book, to me, its mediocre. Besides the over-sexual Starfire, the constantly angry Red Hood, and the stupidly carefree Arsenal, the book has a few things that has got me wondering, and they follow as:
a) When will Starfire and Nightwing meet up? Is there any news? I actually don't collect this series, but I would PAY to see how that goes down.
How the hell is he alive after doing this?! and also, couldn't he power up his demonic swords with the blood of his enemy/ some random bypasser (since he's obviously displayed no intention to do good).
