It might be the lowest of the billion dollar movies in financial terms (still nothing to be sniffed at, obviously), but The Dark Knight is the best of the bunch, and has a good chance of being one of the greatest films of all time.
For a lot of people, the film cannot be separated from the tragedy of Heath Ledger - which may have helped it at the box office in a similar way to Paul Walker's death linking to Furious 7's success - and there is a compelling argument to suggest Ledger is the most irresistible part of the film. The fact that there were rumours that the role may have contributed to his death added another level of interest.
But the film is a lot more than just his performance of the sad context of his death: it's a great action movie (though probably not a superhero movie per se), a great escalation of what Batman Begins established and a thrilling ride. And Ledger is only one great performance among many.
