Why is "Cap's Kooky Quartet" so much better respected, so much more fondly remembered, than "Justice League Detroit"?
In Avengers #16, Iron Man, Thor, Giant-Man and the Wasp left the team, and Captain America was left to run "Earth's Mightiest Heroes" with B-characters and former villains: Hawkeye, Quicksilver and the Scarlet Witch. In Justice League Annual #2, Aquaman dissolved the Justice League, moved their headquarters to Detroit, and brought in a bunch of new characters: Vibe, Steel, Gypsy, Vixen.
It's easy to pick on both teams--heck, Dwayne McDuffie regular dissed on the weakness of JLD during his Justice League run, and because he wasn't allowed to use DC's big guns, he publicly complained the he was stuck with "Cap's Kooky Quartet...without Cap."
I think that the weakness of both teams are greatly exaggerated. Sure, CKQ wasn't the most overpowering line-up ever. But functionally they were the Marvel equivalent of Batman, Green Arrow, Flash and Zatanna. I think most people would be happy with that line-up, at least for awhile.
As to JLD, people like to focus on "the kids," but they almost always overlook that Aquaman, J'onn J'onzz, Zatanna, and Elongated Man were part of the team, too. So it was never "just" the kids.
Still, if you talk to the average fan, CKQ is going to be held in much higher esteem than JLD. Why? Here's some reasons, methinks:
**Nostalgia: Cap's Quirky Quartet took place in the Silver Age, before most modern fans were reading comics. A hazy mist of "the good old days" has settled over those Avengers days. JLD, however, took place in "modern" times (at least for us old farts--the 30th anniversary of JLD is in a couple of years!). Experiencing JLD "live," as it were, in a more cynical era, it didn't have that nostalgic magic. Plus, a growing comics press and fan presence ensured that every negative thought on the JLD was more widely circulated than would have been the case in the 60s.
Plus, the circumstances made Cap more sympathetic. The other Avengers chose to leave, whereas Aquaman haughtily "fired" the rest of the Justice Leaguers. And, to make matters worse, after he had dismissed the "classic" Leaguers for not being willing to commit themselves 100% to the League, he got swept up with personal problems and quit the new League himself.
**Writing: Stan vs. Gerry Conway. 'Nuff said.
I must be fair here, and note that the "newness" of the "kids" has always been exaggerated. Vixen had nearly debuted in her own comic in 1978, before the DC Implosion caused it never to be published, and had debuted in 1981 in a Superman story. Steel was really a spin-off, as Gerry Conway had written a WWII-based Steel series in 1978, which was another victim of the 1978 Implosion. Conway made this "new" Steel the original's grandson. Only Gypsy and Vibe were truly new, and as noted above, there were plenty of veteran Leaguers around during the JLD era.
And thematics aside, Conway and DC should be lauded for putting together one of the most diverse teams ever up to that point...even if that means having to put up with Vibe.
**Length: This will surprise many, but CKQ lasted barely a year. The Pym's rejoined the team in #28, making it a sextet. Hercules came along not much later. Whatever pain and weakness the Kooky Quartet inflicted upon the public, it wasn't long lasting.
JLD, however, lasted for 2 1/2 years. If CQK were a recession, JLD was the Great Depression.
Well, that was an awful lot of words just to confirm--Cap's Kooky Quartet kicked Justice League Detroit's ass.
