Merch:
-Articulated figures, a la their All Stars line, of Cassandra Cain as Black Bat. Heck, I’d also spring for one of her in that get-up she had in Hong Kong for a time, where she didn’t seem to have a codename. They don’t need elaborate sets or anything, like the Young Justice figures, just some stand-plates, either shaped like, or engraved with, a bat emblem.
-Funko POPS of Cass in her various (pre-Flashpoint) identities.
-Maybe a re-release of the Steph Batgirl figure, but she comes with her own Bat-pod.
Live action TV:
-Better writing, in particular for Flash and Supergirl. Probably too much to hope they already initiated that directive for the upcoming seasons, though.
-Also, you should win things just by watching–oops, sorry, that’s another thing.
Comics:
-Dan Didio given his walking papers, and Jim Lee either ousted as well, or at least removed from authority.
--Addendum to above: Dan's last act can be to record himself reciting the entire essay, "The Case Against Dan Didio" for DC's YouTube channel. If he resists, he gets mauled back in line by Alan Moore's beard.
-Reinstating the pre-Flashpoint origins and histories for Cassandra Cain, David Cain, Jean-Paul Valley, Stephanie Brown--Shiva, too, probably, since I think she got reinvented as well. Not out of some big admiration for the character, it just wouldn't surprise me if her retcon was as lackluster as all the others.
–Addendum to above: If you’re having trouble figuring out how to make that work, give me a call*; I work for less than some of your lousier writers.
-Knock off the “dramatic” or “shocking” deaths. We all know you won’t keep them dead, even if you want to. It’s tedious and boring. Not to mention, some characters are fine, just underutilized (or written by the wrong writer).
*No, I don’t expect them to actually contact me, but it never hurts to try. Unless you’re trying to lick your own elbow; that can lead to injury–especially if you’re successful.
