Don’t Stray Away From The Comics
The team of Berlanti and Guggenheim have proven that not only can they get us to care about lesser villains but also characters that nobody would think could work on screen. The prime example of that is in this season of The Flash. Ralph Dibny, a.k.a. the Elongated Man, has become one of my favorite parts of the show and not only has his character got me but so has his arch of redeeming himself from being a sleazy PI. It’s a great example of the talent that is boosting these shows.
The reason I think that’s the case is the producers behind these shows don’t stray away from the comics. They still have one foot in the comics history and the other in a way that fits the story. I don’t want the Arrowverse version of Batman to be like Gotham‘s. I think staying in the canon of the books and taking some slight creative liberties to fit the story is the best way to fit Batman in the Arrowverse.
