The whole point of breaking the fourth wall is that it shatters any "in." It has a character openly acknowledge he is in a movie/play/comic or what have you and address the audience.
Yeah, I guess you could say they were knocking on the fourth wall with that one, but not breaking it.

And yes, Ra's is one of Batman's main rogues. He's not as popular as Joker, Two-Face, or Riddler with general audiences, but he's still a main rogue.
I think fans were more forgiving of it because the end result was Liam Neeson playing Ra's al Ghul, which is kind of awesome and fitting. It was more of an "Oh I should've seen that coming!" sort of thing. I mean he was sporting the goatee the whole movie.
