I just don't like having a Justice League team where that's all you get. So you can prolly tell I'm not big on the Detroit era.
Hey, I live in the Detroit area and didn't care for it much at all.
The problem is that trying to keep continuity between the JLA and the characters who have their own books is hard stuff. Superman's initial JLA adventures were almost in a separate reality from what happened in his own books. Add Batman, GL, Flash, etc. and it just gets nasty.
Setting up the book JLU style would give ya the best of all IMO. Plus I liked that there was usually at least one Big 7 person present which made for some interesting contrast. I hope by my evoking the animated series stuff so much I'm not coming across as saying it's the end all/be all. Those shows have some of their own problems to. But I think they made some really good decisions more often than not especially when compared to roads the comics have gone down which just baffle me.
The DCAU works because there's one big point of control. You don't have S:TAS and B:TAS events happening at the same time that crash with each other. It took them awhile to get to JLU, and there were stumbling blocks along the way. I'm glad to see that McDuffie appears to be going in that direction.
