2. Give Wonder Woman Her Own Movie
Even though I want to include Arrow in the JLA universe, I think Wonder Woman deserves a little more attention than a television series. CW's Amazon would be fine as an introduction, but in order to become an integral part of the team, Princess Diana needs her own feature film. The success of The Hunger Games has shown that audiences are ready for strong female characters, and this is where Wonder Woman could shine. It's all but confirmed that she will make an appearance in Man of Steel, so why not use that as a launchpad for a solo film instead of going straight into JLA? Wonder Woman is equally as important as Batman and Superman, so she needs a good story arc. There's no point in just throwing her into the action. She needs to grow as a character in much the same way as Superman needs to accept his responsibility. The Avengers failed in this regard, but to be brutally honest, Black Widow is expendable compared to Wonder Woman. If DC get her wrong, it could ruin the entire movie.
