For those who haven't seen the show, it is AMAZING! The action is excellently choreographed and maintains a reality that surpasses most current blockbusters, and I'm not just hyping it, the fights are unique and have a weight and reality to them while feeling fresh and like we haven't seen them done this way before. The characters are each well-defined and unique and the character development is well balanced, giving us a bit of new insight each episode as well as having some building love interests just to keep things fun. The stories are drawn right from the comics but are given a dimension of reality that finds them feeling adult. The animation is top notch and overall this show breathes new life into the DC Universe, which has been feeling a bit stale for most since Justice League Unlimited ended.
Volume 3 has four episodes (#9-12) from the first season, and features the kids facing Psimon (of the Fearsome Five), Lex Luthor, Ra's al Ghul, Sportsmaster, Cheshire, the villains at Belle Reve Penitentiary, and Red Tornado's "siblings" Red Torpedo and Red Inferno. The kids are also seen in their high school environments with cameo appearances from other DC teens like Mal Duncan and Karen Beecher (from the original Teen Titans), Wendy and Marvin, (yes, THAT Wendy and Marvin, but NO Wonderdog), and Bette Kane and Barbara Gordon. The only Special Feature is a Digital Comic Book reprint of a few pages and panels from Young Justice #0 that you can page through screen by screen. For those of you who don't collect comics, this particular issue takes place just before the end of Episode #2, so it's almost like watching storyboards of deleted scenes.
Overall, if you enjoy this series, you will enjoy the DVD. The only real negative is the DVD release strategy of putting out episodes four at a time.
