Batman is appearing in Wonder Woman 20 by Tom King. Tom already wrote Batman and is an expert on both characters. Them being in a relationship will allow Tom to write both simultaneously, give his Batman fans new content, and blossom one of the most anticipated couples of all time.

"one of the most anticipated couples of all time"

Anticipated by who?

Not by any Wonder Woman fan.

DCAU fans

Well the DCAU didn’t get everything right.

Tell me about it. Mark Waid talked about how the writers of Superman: The Animated Series felt like children being forced into doing homework they didn't like and that they'd much rather work on Batman instead. Bruce Timm was a huge Batman fanboy and that was especially obvious during crossovers, which depicted Batman running circles around Superman.

I'm starting to think that maybe Timm shouldn't be involved in the new DCU.

I honestly only liked the DCAU because they actually had a huge Justice League. It could’ve been done so much better and is highly overrated. I don’t even like the way they handled characters like Catwoman and Aquaman. Plus giving Kara Lindas outfit and mashing up Superboy and Powergirl? No thank you. Unfortunately it is still some of the best material we’ve gotten from DC outside of comics.

The Bruce-Babs ship is another thing Timm needs to stop doing.

Wonder Woman was treated fairly poor in JL too. Pointless new origin, her storylines didn't really feature her villains, and the villains that were featured were nothing like the original (Cheetah? Giganta?).

Facts but I honestly don’t mind DCAU Cheetah and Giganta.

To be fair, Timm's opinions on Superman gradually softened after the release of Superman: The Animated Series, which is fine for me because that show was amazing. It still holds up after so many years and it definitely blows My Adventures with Superman out of the water.

Does Timm still prefer Batman over Superman? Obviously, but just because Timm likes Batman doesn't mean he's obligated to dislike Superman. These characters can go together if you let them.
