7. Batman Beyond
Ever since the animated series Batman Beyond aired to fan acclaim from 1999-2001, there has been a lot of talk of a live-action version, with a movie even being mooted in the days before Batman Begins restarted the franchise. However, now that we have a Batman prequel series already on the air with Gotham, it is a perfect time to do a Batman sequel series and bring this long touted project to fruition. As in the animated show, the series would be set in a sci-fi future Gotham where an elderly Bruce Wayne trains up wayward teen Terry McGinnis to take up the mantle of Batman. A live-action Batman Beyond of any kind would be a very fresh take on the mythos and a TV series is the best option for it so as to allow for an exploration of this future world and what has happened to it since the crimefighting career of Bruce. For example, the gradual teasing of the tragic tale of why Bruce quit being Batman immediately offers itself as an ongoing story arc.
