I hope he goes full Batman in this show. It'd be nice to look at a television Batman show again.
Also, I am aware of DC's idea of keeping TV and movies separate but there are certain shows they can produce that can allow them to hit the ground running when it comes to a new movie like re-introducing Booster Gold to casual TV watchers then hit them with the movie.
Also, it'd be sweet if Gotham became a movie where they show a different take on Year One.
