Look, I thought The Dark Knight had a lot of strong selling points: Combine a deft pace with thoughtful characterizations and a whopping IMAX design that turns the entire experience into a plot-driven theme park ride, and you've got one hefty dose of Batman adrenaline.
Still, comparisons to The Godfather Part IInotwithstanding, The Dark Knight isn't foolproof -- in fact, no single movie in history is foolproof. The subjective experience of movie watching ensures that nothing can be universally liked by everyone, and rules of civility insist that humanity respect that truism. It's acceptable to feel passionately about a great work of art, and defend that perspective with rigorous argumentation, but much of the outrage over the minority perspective that The Dark Knight isn't any good has made such practical thinking impossible.
Deemed the first critic to pan the movie, New York's David Edelstein went out of his way to list the allegations against him sent along by various Batman fans. The House Next Door editor Keith Uhlich, meanwhile, fielded over a hundred rants in the comments section following his astute critique of director Christopher Nolan's questionable portrayals of violence. What's particularly shocking about this frightful deluge of negative responses is that many of these people began posting their disapproval before they even saw the movie.
