This was a fantastic episode. I laughed a lot during it.
The intro was great. Man is Booster Gold an idiot. It was nice to see Riddler for the first time.
The highlight of the episode of course was Batman being split into three parts. Dietrich Bader pulls it off fantastically. Science Batman was a total nerd and spoke like one. Angry Batman was violent and was ready to fight any villain he can find. Slacker Batman was the highlight thought. So much fun seeing Batman act like a stoner. I'm not familiar with firestorm or Dr. Eks, but both made for a fun episode.
I had lots of fun with this episode and that is what matters in the end.
