I think the show captures a distinct side of Batman, and thats his roots. While still bringing us classic moments never before seen on the the Animated Series, and JLU.
The old fans griping has been really annoying in my opinion. Dini doing some episodes will give us fans of the show a little ammunition.
Batman. and JLU were great, but they never tackled Guy Gardner, Plastic Man, Batmite, or the Golden Age Flash, and other characters. Brave, and the bold embraces DC for all it's glory, and not just this so called "dark" box that a small group of fans have tried to paint the Universe into.
For those that truly read DC, you know that it's cheesey bygone era's and Golden Age fit right into that Darkness, it's not some hidden part of the past it's part of it in all it's glory.
