I agree. As I have said, the fact that Batman TAS, its related movies and webisodes, Superman TAS, Batman Beyond, the Zeta Project, Static Shock, Justice League, AND Justice League Unlimited ALL were in the same continuity over a 14 year period shows that it can be done, and done WELL.

I'd agree that comic books shouldn't have to follow such a strict continuity considering how long they last and writers can always retcon things, but to not hold continuity in a single cartoon series, that sense insane. Well, I get this is a new series and it doesn't have to follow another one, but then why tease the fact that it does talk about it being a continuation? Which is something Loeb did before this started.

A lot of modern comic writers, Loeb included, but also Brian Michael Bendis, Brad Meltzer, and Grant Morrison are of the opinion that canon is fluid, the same way mythology is. So they really don't care, and explicity say they don't care if new stories directly contradict old ones. This is distinct from the John Byrne types, who ret-con old stories. Loeb et al say older stories don't matter.
The argument is that "why should a writer in 2013 be limited by what Roy Thomas or Gerry Conway wrote in 1968?"
I get that for JLA characters who have appeared in literally thousands of comics, but in a self-contained cartoon series that will have maybe a TOTAL of 100 episodes its easy to maintain continuity.
See for example the DCAU from 1992-2006.

Yeah, I didn't get if it was canon or if it was just a little nod to a better series. If it is a continuation, then we're are Ms Marvel, Vision, Black Panther, Wasp and Yellowjacket? Did they just tell Tony get screw off when he reformed the team?

Wrong. As other threads have pointed out, this flashback only confused the continuity question. At various times Joseph Loeb and others have said this is a reboot in the USM universe, a reboot NOT in the USM universe,a continuation of EMH, and a follow up to the movie.
Its just muddled now.

Seemed forced to me.

It was nice to see, and made me realize just how much I miss the show.
