Picking the top 10 DVD/Blu-ray movies of 2010 is a lot different than picking the top 10 movies of the year. I'm not saying artistic quality doesn't matter on DVD. What I am saying is that the quality of the DVD image and digital sound counts just as much as the quality of the film. I'm looking for the WOW factor — DVD movies that rock the house, whether you're watching them on a high-end home theater system or on your computer screen. And it's not all showboating. A great DVD transfer can capture the play of light and shadow in a movie of hushed intimacy. So, here they are: the 10 best DVDs of the year, with references to key scenes that demonstrate what DVD picture and sound can really deliver.
