How would you like it if some of the DC heroes where separated by different companies and they couldn't do a Justice League movie because they have different companies and then tell you that it will happen when they run out of ideas, would you like that or would you hate that?

As I said, if there are already good quality cinematic universes established, I wouldn't really mind if there wasn't a Justice League in the near future. I would prefer for the already universes to run their course and have a natural ending, rather than abruptly end them and start from scratch again just to make a mashup movie. Luckily, that's not the case with D.C. :D
