James Berardinelli reviews Nolan's epic:
Batman is more heroic, more flawed, and more conflicted than in either of the previous two movies. At times, he makes Hamlet look decisive. In the end, we get the character we yearn for, but a lot has to happen for the movie to get to that point. Jonathan Nolan admits to having been influenced by Charles Dickens' A Tale of Two Cities when writing The Dark Knight Rises, but one line more than any other became the seed that germinated the final story. You don't have to wonder about it; it's referenced explicitly.
Sigh. I haven't read that work of Charles Dickens.
