If you happen to be on the fence about purchasing the Blu-ray due to the potential for a double-dip, you’d be missing out on a great addition to your high-def library; however, it would certainly be understandable as the features for The Dark Knight leave quite a bit to be desired for such a landmark film. That said, the video and audio on the Blu-ray disc more than make up for the lack of features and make The Dark Knight, already a great film in whatever format you happen to view it, a great way to show off your hi-def system.
