Eh, it's got spunk but I'm having a hard time really caring. The action is decent and the characters are really fun, but there's not much in the way of drama, stakes, or character relationships. Granted, I suppose those could develop over time, as the characters do all have a lot of, well, character.
Rookie Batman, Batman and Barda, and Firestorm are definitely the most humorous parts so far imo. Jimmy got a grin out of me. Space Cabbie was just too dead-wife-y.
