The DCU lol. But in all seriousness I’d say YJ.

My heart wants me to say 90s Flash, but my fully functioning brain remembers that show, and thinks it had no hope (unless they really upped the villains). My other organs have no real opinion.

Batman Beyond

Young Justice. I very love that universe and the characters within it. I want a Season 5.

DCAU, with the exception of Batman Beyond and Barbra dating Bruce, the DCAU is the best long term adaptation we’ve gotten in these last 30 years

Wow, first person other than me I’ve seen say that they don't like Batman Beyond.

I’m so not a fan, like what we’re supposed to just assume the hundreds of heroes that failed to be mentioned died or retired?

The creators who made Batman Beyond don’t even like it that much. Bruce Timm said out of everything they made Batman Beyond had the worst writing, while Alan Burnett said it wasn’t a Batman cartoon it was a Spiderman cartoon disguised as a Batman cartoon. Which is spot on given how many people want a Batman Beyond movie in the style of into the Spiderverse. Batman Beyond is a perfect example of the warped and twisted version of Batman that Bill Finger and Bob Kane had issues with, it’s simply not Batman

Do you have any confirmation of Timm saying that he didn't like Batman Beyond?

The best “evidence” I can find is someone on reddit saying he said it was “uneven”.

That's it? "Uneven"? That's just a criticism. It's not an outright condemnation.

Now, I can understand why people would call Batman Beyond a Spider-Man ripoff because Spider-Man is the prime example of a teenage superhero (I myself have referred to Smallville as a Spider-Man show with a Superman veneer), but that doesn't diminish its value as a piece of entertainment.

Stories and characters are created when creators take elements from previous stories and mix them up to form something new, lest we forget Superman was inspired by the stories of Hercules, Moses and Samson.
