I'd love to see a more standalone Batman movie with Tilda Swinton in the role of The Riddler.

Nygma (the last name devised by his father, but not truly his last name) moved through his life adopting and shedding persona, always relatively on the run, in fear that he would be found and possibly be implicated for the killing of his father and siblings. In what ultimately was a bad decision on his part, he fell in love, had a couple kids of his own and tried to stay off the radar. It didn't work.

The Falcone Syndicate, struggling but persistent, found out Nygma's (or rather Janusson's at this point) secret. His wife was found murdered but he could not come out to identify her, partly to protect his children and partly to protect his secret. It hardly mattered. She was killed to connect with him and the Falcone mob does. They now know who he is, who his kids are and where they are. They will use his survivalist training and instincts as a top-notch hitman and everyone stays safe. If he doesn't accept, their lives are resigned to constant terror and imminent death. Janusson will be the puppet.

But he will also leave messages behind, both at once toying with the law (and Batman) to find him as well as offering clues to the bigger picture, who is really behind these crimes, hopefully devising an endrun to get the puppet master before the Batman or the puppet master gets him (and his kids).

Now, with all this in mind, DiCaprio was the only person who could have pulled off this Riddler because the Riddler was, in many respects, like the character he played in Catch Me If You Can, Frank Abignale. But all involved went in another direction much to my disappointment. You can't win them all.
