That Nightwing is one of Batman's sidekicks.
That the Adam West Batman is as valid an interpretation of the character as any other. I'm sorry, but the Adam West show was a PARODY, not a "real" depiction of the character. The comics never treated him as the campy joke that show made him out to be, not even the cheesy 60s comics. I'm not saying it was a bad show or that you can't like it, but to treat it as anything other than what it is (a parody that pokes fun at the character and the medium) is just wrong in my book.
That Byrne's "humanized" version of Superman in which Clark Kent is the real person and Superman is a mask is the only interesting interpretation of Superman, or the first interesting one. To that I say rubbish. Before Byrne stepped in, writers had made Superman interesting by playing on his sense of loneliness and feeling of being different that came from being the only Kryptonian (*cough*) left in the universe. In fact, I found that version more interesting than Byrne's "average Joe with superpowers", as well as more original (Marvel had already done that).
That "modern" (read: post-80s) depictions of Batman suck and are inferior to O'neil's as they make him too boring, perfect, emotion-less and dickish. First, just because he acts stoic it doesn't mean he has no emotions; just that he choose to hide them, as showing emotions and weakness doesn't go with the image he's trying to show in order to scare villains. Second, his dickish, dark and antisocial behavior is part of what makes him flawed and thus interesting. By comparison, Batman from the 80s and before was a pretty generic character in terms of personality. And third, since he's flawed due to the aforementioned reasons, you can't accuse him of being perfect (except for the cases in which writers make him Bat-god).
