In the show Young Justice, we get a look into an element of the DC universe that we haven't had a chance to see in depth on a cinematic scale.
The Core Element of Young Justice, and the reason it is so interesting and unique, is being able to watch the transition from a Sidekick to a Superhero in every detail.
We've been able to see the set in their ways role of a Superhero like Batman, they have experience and a rich back story along with so much charisma, sympathy, purpose along with a few skeletons in the closet of course and they're amazing for it. However they are already defined as that character, we know who they are, what they do and why they do it.
With Young Justice we get to see the Hero's discover themselves and transition into the roles they are destined to fullfill, we get to follow them as they develop their backstory, build their charisma, fears, goals and are a part of that experience with them. Your able to grow attached to these characters in a way that you'd never be able to with the already defined heroes.
The writers of Young Justice have done an amazing job so far, to make a third season would be the first step to making something great, and with the fan base they have supporting them I know this will be a well known and memorable part of the DC universe for generations, fans around the world will have another shining example of the simple fact that: Comics. Are. Awesome.
