This was one of the early Blu-Ray releases. Since then, optimizations to visual quality have been made (new codecs and such) to newer Blu-Ray titles. The Dark Knight is one of the more eye popping Blu-Ray's I own that I feel justifies owning a Blu-Ray player. Black Hawk Down on the other hand, is not. There's too much yellow shine in many of the scenes and film grain is literally everywhere on the screen for the entirety of the movie. Compared to the DVD version (which my dad owns), I honestly prefer it over the Blu-Ray version (and I only paid $4 for this on clearance). That being said, the sound quality is excellent and would be one of the few redeeming qualities of this version (though the DVD wasn't too far behind).
What's great about it: Sound quality is very good
What's not so great: Picture quality isn't too much of an upgrade over the DVD version
