Slade specifically being there is a source of annoyance for me. I hate shoehorning him into the Bat-Verse in general, unless it is in some way connected to Dick. Slade is a contender for Dick's arch nemesis, he doesn't need to lose yet another thing to his more popular Bat-Dad. Especially when Bruce already has the "arch nemesis" thing covered in spades, while Dick can't even hold onto one for very long. Slade showing up in Morrison's Batman & Robin was a good use of the character, and is more of what I'm looking for. Also, Slade's a bastard but I don't think it's in character at all for him to draw attention to himself like that by fighting Deadshot and wiping out so many civilians. However, I do not have a problem with Bruce taking him out in a surprise attack after 5 straight days of fighting. I've made it no secret that I do not care for God Mode Deathstroke, AKA the guy who couldn't kill the Teen Titans.
In general, I don't like the fact that all the villains are there that early in Batman's career pre-Robin. There was practically nobody left to appear. Two-Face in particular stood out, I always feel like he should appear later than a lot of the other major names to give Harvey Dent some time as a supporting player before **** goes south. It kind of reminds me of Jeph Loeb's tendency to throw as many villains as possible into a story regardless of whether or not it makes sense. However, unlike Loeb, when King focuses on them individually as characters (Kite-Man of all people especially, but also Ivy, Bane and the Ventriloquist) he has some more interesting things to say.
I don't think it's hard to have a better grasp on Diana than Robinson
. Her sounding robotic was a common complaint for her by some WW fans, but that's just King's dialogue combined with the way Diana usually speaks since Perez. She's always in "Regal" mode when handled by most writers, with a much less relaxed way of speaking. I like and respect that he acknowledged the mistake, and I'd be pretty happy if he was announced as taking over her book. Referencing Jumpa gains him many brownie points. If unleashed on her universe, what other obscure stuff would he bring back?
I hope he did the Ivy thing because it was always his plan.
IDK, it's probably down to needing to read the full story once it's out in its proper context instead of rushing through it in the store and reading scans on line. I usually like the Joker to engage in more "creative" (for lack of a better word) terror than just shooting people. I feel it's too common for the character. But it is also unfortunately not without precedent, so King is not guilty of doing some unheard of thing (like he isn't in general, despite what some would say). But I used to dislike Morrison's Joker until something eventually clicked, and now I love him. Maybe King's will be the same? I might eventually come around to Snyder's Joker as well.
