Just in time for the holidays and the strange questions of why didn't the show come out months earlier, Justice League Action has another new premiere date December 16 at 6:00 P.M., then new episodes start coming out Saturday mornings, all on Cartoon Network. A netwoek who seemingly hates WB and DC comics, but has to do what they're told because Teen Titans Go! is their most popular show.
The reason for the shows delay must be on the corporate side as the animation had to have been done months ago. Best guess...because it would be making quarterly reports look nice for more viewers in the next year. Or...just executive stupidity.
Anyway Batman, Superman and cool-as-Hell-looking Wonder Woman will be kicking butt this December.
