Justice League Action Ep1-3
Justice League Action already premiered in UK and someone posted first 3 episodes on illegal websites.
At 11 minutes, it is tough to say if there is really any special in this show. If you are looking for something to develop characters and plots, you may want to go and look else were. The animation is basic, but good and is better than the garbage that is Teen Titans Go, especially when you have such a godly cast of voice actors. this could be an easy introduction show for kids to the world of DC.
