Eh, I don't really care about all of that. Feels out of sorts is a far distant second to very good and awesome show. And I loved the JL gag at the end, it was a good joke.
That said I do agree on being fine with everything being standalone too, but then that has always been my stance. Seriously, the posts disappeared when the forum rebooted, but I was like the only one arguing against DC going the shared universe route back in the lead up to Man of Steel. I've never needed a cinematic universe and getting everything connected. I imagine all the better films we could have happened. But eh, no point in crying over spilled universes. I like what we've got ever since Birds of Prey, even Wonder Woman 84 (I really thought it was pretty good).
