To clarify, Yoc, my problem with the JL show wasn't a continuity issue so much as storytelling and characterization. The episodes seemed (and still seem) to mostly be setup for yet another "epic battle." There's what I consider a pretty weird obsession with Lex Luthor and the Fourth World stuff that don't really work for me as "Justice League" stories.
And then the heroes are all...kinda jerks, especially Superman. They're also terrible at whatever it is the Justice League is supposed to do. I just watched the first half of the "authoritarian League" episode, and had to laugh at the shock that Superman would kill someone, after spending the pilot literally pulping Martians and the time-travel episode crashing Nazi troop carriers that were filled with soldiers, and nobody bats an eyelash. (Also, they get knocked out by everything. I mean, c'mon, how clumsy can these idiots be and still be allowed on the streets...?)
Jim nailed it with the Flash. The costume stinks (and the muscles aren't even supposed to be the character's, making it baffling), and the casting wasn't always a good visual match. But it reimagined the character for a different genre, and it did a really good job of building a fresh background. I would've loved to have seen it grow into the era of TV police procedurals, since it was already flirting with the idea in a lot of episodes (unsurprisingly, given Barry's day job).
For a while, I was trying the Green Lantern series (with the gaudy computer animation) and the new Young Justice series. They were nothing to write home about either way, but the "DC Nation" shorts had some good stuff. A lot like the B&B teaser episodes, they're mostly just a couple of minutes for some obscure character, and quite a few that I saw were very good. The Amethyst spot could easily be expanded to a series that'd get a lot of attention.
