one of the things I like about this series is as an adaptation of the DC universe as a whole, they decided to compress the superhero groups and by that I mean instead of having like half of the 10 or so groups that gave existed throughout the comics and kept the essentials, being the justice league as the group of adult heroes, the justice society as the no longer active group preceeding it and a group of young heroes associated with the JLA but still seperate which can be viewed as a combination of various groups such as young justice and teen titans.
