Frankly, I don't think DiDio has done a great job overall. It's not simply that I don't agree with his creative choices - which I often don't, but those are his decisions to make - it's that I don't think he always carries them out very well. But that's just my two cents.
Anyway, here's more insight from a comic writer about DiDio's rise to power (quoting Patrick Gerard from another thread):
"- Underpinning a lot of this stuff is, from what I gather, Paul Levitz was trying to choose a successor to run DC. Except what a variety of folks did or did not know was that Dan DiDio had been handpicked by somebody at Warner Bros. to take over DC before he wrote his first comic. The only reason DiDio showed up in the first place was to run the company the way WB wanted. Levitz didn't know or didn't get the full memo and was trying to find alternative candidates to weigh against DiDio. Levitz interviewed Waid. I think he talked to Loeb. Loeb and Waid always got along FAIRLY well.
- But everybody who interviewed for Levitz's job had issues with DiDio. It's hard and probably unfair to assign blame on a message board post without all the facts but DiDio was trying to move into a job he'd been promised maybe 5 years before. Meanwhile, you had competing offers made to other people that upset DiDio, who spent five-plus years of his life turning down other work, planning to take that job. It became hard for some of these people to work together for awhile. So you had a big exodus from DC to Marvel of people who, I think, had awkward relationships with DiDio largely because of conflict between Levitz and Kevin Tsujihara and some other folks. Diane Nelson was brought in, in part, I think, because of how frayed the WB/DC relationships were so she could be a neutral party -- and because she was seen as being able to expand the young girls and Young Adult markets based on her background with Harry Potter and other stuff.
- On top of all of this is that I think there's a lot of folks who misread DiDio in part because, well... He's a troll. A bonafied troll. Yes, he wanted Nightwing dead for years and planned it various ways. But all the stuff about hating Nightwing was playacting. He did it because he thought it would upset the most people. He has a very soap opera/pro-wrestling view and he's more of a Silver-Age/Bronze-Age Marvel guy than DC. So he's always trying to inject that 70s Marvel "Hank Pym becomes a wifebeater" type stuff in. Because he has a view that the more comics upset or provoke people, the more they sell. Honestly, if he wants a character dead, he probably likes that character and is picking on them because he wants to stir up pitchforks and torches. He's backed off that SOME largely because outrage works differently online now. But he operates very much from kind of a Bill Jemas worldview: "If you're happy with what we're doing, our sales will suffer." That's... a difficult thing for some folks IN COMICS to mesh with. Some folks just want a clean and fairly neutral status quo so they can tell clever one off stories kind of like Batman: The Animated Series.
In some ways, Loeb and DiDio got along super-well. DiDio greenlit stuff Levitz probably wouldn't have. He hired Loeb for All-Star Batman. (Frank Miller was a replacement hire. There's a first issue in a drawer somewhere of a Loeb/Art Adams All-Star Batman #1.) But he also made Loeb's job harder and kept wanting to tinker with some things in the opposite direction.
Loeb was always trying to fuse the Byrne continuity with the Silver-Age so that you'd just have one 75 year Superman continuity like what Morrison later did with Batman. DiDio wasn't keen on that and neither was Waid, exactly. Waid loves the Silver Age as a fan but he's the first guy to throw it into the woodchipper if he thinks something is silly, unrealistic, or embarrassing. (Johns shared an office with Loeb.)
The tug of war gave us Superman origin reboots about every 18 months. And Loeb more or less walked from the monthly Superman book at the start of that because he wanted a stable run."
