Batman: The Killing Joke Romance Impressions

Now, I haven't seen the Killing Joke, but I've gathered details from every review out there to sum up, the romance between Batgirl and Batman.

First the romance between Batgirl and Batman, good god...no! If anything could have been more mischaracterized, it would be the romance. And when the kissing scene happens, Batgirl is more than 20 years less than Batman! In some places, it's illegal to have sex! And not only that, neither Batman or Batgirl would ever do this, they are too professional and take pride in their work!
