I really, really wanted to like the episode, because I actually thought the parts with Gordon were pretty cool. But to be honest, the shoehorning of future Batman villains was just ridiculously distracting. I think my eyes rolled into the back of my head. Remember that scene at the end of Rises where we learn that one guy's name was actually "Robin"? It was like that, except several times worse. The episode just winked and nudged so hard that I think I ruptured a kidney.
I knew that they would appear in the show, but I figured it would be handled a little more subtly.
