I have to admit at first I was closer to how Kirk55555 felt about the villains & sidekick on this, but after talking about it here, and thinking about it more, I've become a lot more excited about getting to see new characters. We've already gotten plenty of shows/games/movies/novels with Robin, Joker, Two-Face, Penguin, Riddler, Batgirl, ect. I think it's about time we let some new characters get some time in the spotlight.
And it's also worth pointing out that in a lot of the interviews, they've said they're starting with these lesser known characters, I don't think they've ruled out the more familiar characters appearing later.
And besides, if they did do the more familiar characters, they'll probably put they're own spin on them that Kirk55555 and people like him will still hate. At least with them doing the new characters, people aren't as likely to be upset about them getting the character "wrong".
