So, no one cares that Nightwing is coming to the show?
I'm excited. I can't wait to see what they do with Nightwing. I think it could be a neat way to have Batman exist in the Arrow universe but not be seen. He could be dead, retired, or otherwise engaged during the events of Arrow. And Nightwing might open the door to Oliver going to Gotham. I would like to see what Gotham would look like in the Arrow universe. Though more than likely he'll just revisit Bludhaven, which is cool too.
Blockbuster could make for a good Arrow villain.
